I’m didn’t read every post, but kind of skimmed, so some of my ideas may be repeats.
Breakfast bake, egg & sausage, egg & bacon, egg & ham/Canadian bacon, etc.
Breakfast burritos
English Muffin with heat & serve sausage patty, egg, and cheese
Oatmeal
Runzas (I remember these growing up, they were like hot pockets but Ma made them with Ham & Cheese, or whatever she had at home. In googling for a recipe, all I could find were ground beef and cabbage, but other than that they sounded right.) These froze really well.
Shredded BBQ Pork or Beef. Made in a crockpot, actually have this cooking at home right now.
Chili I also make this in a crockpot
Homemade Soup
Lasagna, or really any casserole. We usually make two pans of lasagna at a time and freeze one of them for later.
Chicken cooked in a crockpot
Tuna Pasta salad is a favorite of mine
Salad, can mix this up with different dressings/toppings. I usually toss chicken, turkey, ham, tuna, or whatever meat I seem to have leftover on it.
Homemade pizza. I make a huge pan of this and leftovers are quick and easy and filling. (more filling than store bought pizza)
Wraps, tortilla, cheese, meat, veggies. I like Hummus in my wraps too. I need to add that to my grocery list now.
Chicken-grill up some chicken, with basic seasoning. You could also use it for quesadilla’s, soup, salads, etc.
Enchiladas
Tacos
Basically what I would suggest is cooking double some of the meals that you typically cook, and freeze some or just it for lunches the next week. That’s what we do, and both my husband and I rarely eat out for lunch, we typically take leftovers.
One time saving tip that I have is with my veggies for salads/scrambled eggs in the morning, I was and cut them up right away and put them in containers so it’s faster in the mornings. Same with the head of lettuce, I wash and shred that. It seems like if I don’t do this as soon as I get home from the store, I put it off way too long.
Good luck, and if you need any recipes, let me know.
