Three of us have tested positive The fourth will likely do so (just did PCR test today).
I’m working on a grocery delivery order. With all 4 of us likely to be unable to prep anything elaborate, we need idea for very simple meals. Bonus points if it has something for those with anosmia or ageusia - texture, enough salty/sweet/etc to appeal,
Cans of Progresso soup.
Progresso never tastes like much anyway. 
Lots of soup. Coffee and tea. Saltines, peanut butter, apples, grapes. Jello tea is good for coughs, or Throat Coat tea.
Jello tea?
My go-to strategy when I feel a cold coming on is to stop at my local Chinese restaurant and buy a big container of hot-and-sour soup. The thickened broth seems to help me to recover from the cold. (After a while, I’d be asked as soon as I walked up to the place if I wanted hot-and-sour soup, so apparently they noticed my regularity.)
Linguini or thin spaghetti. Alfredo sauce. Vanilla yogurt. Applesauce. Frozen pizza. Orange juice. 7 Up for queasy stomachs.
To make Jello tea, just add a little Jello powder to hot water until it tastes nice to you. The Jello coats your throat and really sooths a sore throat or cough.
This, and these days, pho, although the heat in the hot and sour is good for sinuses. No, you don’t apply it with a neti pot
How simple is simple? When I want to feed the family without significant effort, I do a sheet pan roast. Chop up hearty vegetables like broccoli and carrots and fennel, add a few halved chicken thighs, toss with salt pepper and oil, spread on sheet, roast for 45 mins or so, squeeze of lemon, eat. Takes ten minutes of prep before going in the oven. Is that too much?
Well, if you have the fridge space for a 1 gallon pot [or equivalent in little tupperware containers] a big pot of homemade chicken vegetable and noodle soup [secret is not to put in the noodles but buy the little pouches of already cooked noodles, the shelf stable ones. Dump into bowl, dump soup on top, nuke. That way the noodles dont suck all the liquid up and get mushy]
When I was doing hard core chemo and radiation, we made up a pot of juuk, a pot of rischert and a pot of classic chicken noodle soup [carrots, celery, onion, garlic, chicken] and portioned it out so all I needed ot do was grab one out and nuke it. Portioned it into 8 oz chinese takeout soup containers off amazon.
Juuk - rice gruel - mine is chicken based, garlic, ginger, onion, rice, 5 spice powder more or less cooked til the rice and veg have melted into goo, small chunks of chicken and onions added after
Rischert - ancient Germanic glop - barley, beans, cabbage, turnips [or whatever root veg] carrots, celery, onion, garlic, spinach, pork [or whatever mammal doesn’t get away fast enough. Salmon was not a good idea.]
Classic chicken noodle soup - Jewish Pennicillin =)
All easily digestable, and filling or a light meal depending.
Soda crackers/saltines, rice cakes, toast - something bland and starchy if you are having nausea
Copious amounts of hot or ice beverages - my go to is Bigelow’s lemon-ginger tea, plain ice water, or even gatorade if I need electrolytes and am too lazy to make lemonade.
When I finally caught covid last month (serves me right for going to Vegas and not losing all my money) I got lucky and didn’t lose my sense of taste or smell, but it did hurt to swallow for a few days. I’d recommend plenty of sugar-free Gatorade, Nyquil, Advil, Sudafed, and piping hot soup and to help clear the sinuses. Spicy food (I.e. lots of chili peppers) might be easier to taste than milder foods, and will help with the sinuses as well.
When I had COVID the only thing I suffered from was lack of energy, and even that was rather minor and only lasted a couple days. So easy meals were good, but I was fully up for cooking my usual breakfast of eggs, etc.
Lots of good suggestions! Housemate made some chicken soup the other day and we’ve been living on that. She cooked a bunch of noodles already and we’ve just been scooping those out and dumping the soup on, and warming up the combo. With my messed up taste buds, it’s coming across as bitter, but the warmth and texture are good. It did inspire me to order more chicken, to make some myself with a different, sweeter profile: ginger and cloves in place of other herbs.
I did order tons of canned soup - plus a ton more egg noodles, to make the soup more filling. The jello tea idea is intriguing - could even be done by adding it to actual tea, I imagine - adding flavor (for those who can taste it) and sweetness as well as the throat-coating effect. I’ll have to see if we have any in the house, but in the meantime I’ve added it to the list.
We did pho the other day and it was loooooovely, but that was before my son tested positive. We won’t be doing that again until one of us is out of isolation, since they don’t deliver.
Waiting on housemate’s test results - in a way it’ll be easier if she’s positive, because we won’t have to isolate from each other, and I’ll be better able to do stuff in the kitchen. As the one who’s been on antivirals the longest, I’m hopeful that I’ll feel well enough to do that.
I hope the Jello tea is a comfort. I’m not sure if my post was clear, there is also a commercially available tea bag called Throat Coat tea that is also soothing. I think the Jello is more effective.
One more thought - since you are after a sweeter soup, you may like Thai coconut soup. It has sweetness and a little spice. You can add chicken.
Popsicles?
We JUST did that last night! Spouse is in worse shape than I am, so I called the order in (hot-and-sour soup AND chicken noodle), and picked it up curbside.
Let me know if it seems to help. I think it does for me.
I think I’d just go with a big pot of spaghetti and meatballs. Easy, flavorful and reheats well.
You may not be laid as low as you think, if you’re vaccinated and boosted. My wife and I would have normally attributed it to a cold- its severity was dramatically less than the Flu-A we had in April, and we had to argue with our children to convince them that yes, those “allergies” they had was actually COVID.
I might also just get 5-10 cans of canned soup and a couple packages of crackers. That’s usually a good standby meal as well.
boxed mac & cheese and some hot dogs?
