The easiest best two to three days of food for one person I know of. A flexible modular recipe. This is going to sound high work at times due to how broadly I am writing this, it is not as bad as the vagueness and intentional broadness makes it sound signed a person who has frequently accidentally had sleep for dinner after being unable to make it too damn much.
Rice cooker needed.
Ingredients:
Rice (any), lentils or beans optional (one or two cans), frozen vegetable mix (any and in as much quantity as you want, I like potato, carrot, peas, and corn you like what you like)
Sauces (teriyaki sauce and kewpie mayonnaise is what I swear by because of how easy they are to manage and pour and how well they compliment the food and each other but use whatever you own and can stomach or nothing at all, extra points for one having some fat), seasonings (curry powder and salt is my standard, really the salt is enough) Oil
Additional protein (tuna, cheese, ham, chicken tendies, shredded chicken, tofu, more beans, egg, mushroom, setian, nutritional yeast, you do you, two seperate sources for the different days useful)
In to the rice cooker, put two cups rice with water in proportion, one or two cans lentils or beans if using (strain and quickly rinse them if you can, if not just pour out as much of the liquid as possible and dump), and a lot of frozen vegetable mix in whatever variety you have on hand/like. It's going to look like a lot. That's because it is. This is good. Add more vegetables. Two cups of rice makes more than you think so it's very hard to add too many vegetables to this if you're at least neutral on vegetables. Let the rice cooker cook. It's going to take a while so do whatever.
This is now a mostly complete meal if you add fat and salt, so the teriyaki and kewpie in my version. The additional protein will make it more filling and better in general, so adding a low effort one
Turn off the keep warm on the rice cooker and dump out the leftovers on a plate or something. Or not and just put the whole pot away. Leave in fridge overnight.
If you're ambitious/need variety reheat by frying with a different seasoning and secondary protein source #2 for best results. It's all already cooked so you just need to add the extras and to have it be warm. If you want to then use the fried rice in multiple meals, it reheats in the microwave better than the unfried. If you're not, reheat in the microwave with extras and enjoy that yesterday you making food for today you really helped out today you.
This provides two days of main meal food that are both very presentable and flavoursome, and are sufficiently different to each other it takes a long time to get sick of/makes it easier to feel like you're "doing well". I have had friends compliment me on how nice I am eating despite being in states that would usually leave me struggling to make myself food that mildly disgusts or concerns them. It dirties the rice cooker bowl and paddle, one eating bowl and utensils, one plate (optional), and a frying pan (optional). Most of those I just rinse out or soak not wash properly tbh, it's not like it has cheese to scrub off if you don't use it. This whole process takes about five minutes of active prep and clean up both days. The worst pitfalls I have found with it are getting too ambitious on the secondary protein for day 1 and eventually just having nothing, which I fixed for me by switching to canned tuna or shredded chicken, forgetting or otherwise failing to empty or turn off the heating of the rice cooker, and getting overwhelmed having to use the stove at all day 2 and avoiding the nice but optional upgrade.
I hope this is helpful for someone out there, I know how often most of these from around the place sound "oh my god you think that's simple??" But, and I say this as one of you, the backbone of this is having the machine that boils carbs boil a bunch of carbs for you and cramming as much of a "complete" or "fancy" meal's prep in to that process as possible then finishing with stuff you just pour, drop, or slice in.
Sounds helpful
