Some good suggestions here, including some I'll probably try myself.
I don't like to cook or prepare food. I've decided to embrace that as much as possible -- treat it as a feature, not a bug.
Here are things that work well for me, feeding a family of 3 (2 adults, 1 kid). I surmise that you're a single adult household (?) so will try to focus on things that can be purchased in smallish quantities or frozen.
Buy a rotisserie chicken. I can usually get 2 meals out of a single bird. If there are leftovers, I freeze them and later thaw them and use them pretty much as is, e.g. on a plate + rice, or in a sandwich sliced thin. You can also freeze the chicken before using it at all, then thaw it later.
Buy cooked frozen mussells, thaw/warm, eat. Or buy peeled frozen shrimp, boil or saute if bought raw, melt some butter for dipping, eat.
Put a slab of salmon in the oven at ~350 degrees, warm up 1/4 cup soy sauce in the microwave, stir 1/4 cup brown sugar into it, once it's warm. Drizzle over salmon as it cooks, eat.
Slice up and roast some combination of potatoes/beets/fennel/carrots (any or all). Can be done in any quantity, once cooked, will sit fine in the fridge for about a week and can be eaten on a a serving-by-serving basis.
Cook up some ground beef and/or slice up sausages (fine to buy the already cooked kind or cook 'em) into chunks, add to (store bought) spaghetti sauce, cook spaghetti noodles, eat. Freeze leftover sauce and uncooked meat, thaw and repeat as desired (the noodles won't keep once cooked, chuck 'em. Or keep 'em and eat as leftovers with (a) the spaghetti sauce or (b) fry lightly in oil + garlic and sprinkle with parmesan as a side). You can easily freeze and then thaw ground beef AFTER cooking it (and freeze in packages of pretty much any quantity, having cooked it) so you have it handy for this in a hurry.
Slice up watermelon (or buy pre-sliced), squeeze in small gobs of goat cheese, sprinkle with lemon juice and salt, add some fresh mint if you have it handy, eat.
I rely heavily on frozen veggies -- toss (frozen) into microwave, cook until thawed (no need to add anything, they'll basically steam themselves), top with butter/salt/pepper, eat.
You can cook asparagus (not frozen) and corn-on-the-cob (ditto) in the microwave the same way -- just toss it in and cook 'til done. I usually cook the asparagus a few minutes at a time (add a bit of olive oil to the plate it's sitting on, cover with wax paper or another plate, upside down) until it's done. Corn I just toss in straight, unpeeled, 5 minutes for 3 ears in our microwave, peel once cooked, way easier than the alternative.
So -- pretty much everything listed above can be bought in small quantities (one meal), or divided up if needed and frozen. The exception is the root veggies, but they'll keep forever (more or less) in the fridge.
Hope this helps.
I find embracing the reality that I don't like to cook works much better than thinking I should learn to like cooking.
