Yeah, I definitely realize there's a big tradeoff here. I try to cook extra for each dinner, so that my lunch the following day is leftovers. (3 sameish-meals in a row is rough but 2 is fine by me).

Another thing that's been helpful is big roasts. turkey breast, pork shoulder, etc are very easy to toss a quick seasoning on throw in the oven for 2-6 hours, plus are pretty cheap ($2-$3 a lb, though a bit of that is bone). Gives you some meat to work into all sorts of things for the week with pretty low effort cooking.

With that, a carb staple and random sauteed veg you can get pretty far.
