Ugh I'm with you on not wanting to keep frozen premade food in the freezer (like the Costco pizza). Trader Joe's frozen foods kill me... I usually pick up a few when I shop there (not my regular place, too far away) for those "emergency" days, when stuff happens or I'm just too tired to cook, but when I do that, my willpower plummets, and instead of cooking whatever I had planned, I go home and eat frozen tacos - not because I was too tired to cook, but because I really wanted those damn frozen tacos.
For those lazy, "I just don't wanna cook days," my InstantPot saves the day. I keep frozen chicken breasts, cutlets or something in the freezer, and I'll just throw those in the IP with some spices, sauce or whatever's on hand. I also make homemade pizza burritos - I always have wraps, I always have cheese, I always have tomato sauce, and I almost always have pepperoni. Throw everyone on my cast iron and I get a pizza in a few minutes. I usually just roll it up for ease of eating - again, this is my lazy food :)
I also try to keep a high protein diet, so I always have canned tuna in the kitchen. Mix that up with dill relish, or greek yogurt and spices, and I'm happy. Amazon has a great subscribe and save on an 8 pack for ~$5.
