Oh, yeah! I do that too. 
Nice to see I’m not alone in this.
As a single female living alone, I will tell you that I most certainly do not eat over the sink–because the TV is in the living room.
I eat on my couch, usually macaroni and cheese, out of the same pot I cooked it in–but I do usually go for a new fork rather than the spoon I used to mix it, because the cheese residue is all over that spoon, and you can’t get a good mouthful of mac & cheese on a spoon.
I can cook nutritious, multi-course meals, but then I’d have to wash those dishes. Someday I’ll have a dishwasher, and my mac & cheese days will be over. Nah, who am I kidding? I’ll continue to eat it, because I like it.
Oh, and when I’m done, I also toss the pot into the fridge, fork and all. I have been known to actually throw out perfectly good saucepans and casserole dishes because the seven or eight bucks they cost me don’t seem worth the effort of scraping off the three-week-old former-food they contain.
Well, I was made for courses. I like to have everything properly arranged and laid out. It’s not that I can’t eat standing up, I prefer not to. Salad has to be on a separate plate, I can tolerate the meat & rice on the same plate but I have been known to divide it up, etc. So I don’t think I could ever eat over the sink.
I always eat mac & cheese with a spoon! But with a tablespoon, not some itty-bitty teaspoon.
It’s entirely possible the difficulty lies with my spoon technique, or even with my mouth. I just prefer a fork.
