Bonus points for healthy/low carb. Omivore, vegetarian, vegan, I eat all the things but my autistic ass is very low on spoons. I'm a good cook but even the thought of cooking instant ramen sounds daunting sometimes.
Easy things I've incorporated are protein shakes with coffee, flax milk and chia seeds during the morning. Keeps me good til 1pm or so since breakfast grosses me out during the weekdays and it takes like 2 minutes to prepare
Also wraps. Throw a protein on, condiments or a sauce like pesto or something, rip up some lettuce with your BARE HANDS, and that's it. Or if you're feeling fancy, slice up some cheese/veggies. Less than 5 minutes with minimal clean up, just a cutting board knife, plate and maybe a spoon or butter knife. Sometimes if I'm not cutting much ill just do it carefully in my hands or on my plate to avoid washing the cutting board
Almost any pasta with pre-made sauce
Rice (made in rice cooker), can of beans, salt, pepper, hot sauce, and maybe an avocado if you got one = lots of food for no effort. Can also put frozen veggies in with the rice like others are saying if you want even more food for minimal effort.
I think hummus is pretty low effort, especially if you can just get cans of garbanzo beans (I have to buy mine dry and soak them overnight)
Peanut butter and saltine crackers
Someone said silk tofu with some kind of sauce (usually soy sauce and maybe pickled or regular ginger thrown on top), this is also really good and extremely low effort
E: additionally, it's really easy to make some chocolate pudding using silk tofu and chocolate (preferably melted dark chocolate), can also be used as a pie filling if you want to put in a little more effort
Scrambled tofu is pretty good and low effort if you have frozen veggies, but it's just a little bit more effort since it's best to cook it in a skillet and maybe caramelize some onions to go with it
Honestly this is a lot of my meals. I usually just throw together what ever spices, oils or sauces I have on hand into teacup, mix it a bit and then stir and cook through. My go to this week has been sweet paprika, curry powder, msg, garlic, chilli and soy, fried with olive oil. A little overkill but fuck me if it doesn't slap
