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
Black beans and rice. I drain and rinse can beans and cook in some olive oil with onions and garlic plus whatever seasonings I'm feeling. I'll add about 1/4 cup water to give them a nice little bean sauce and cook them with the lid on. I'll just throw the rice in a bowl and dump a bunch of beans on it sometimes.
