A rice cooker with a steam basket is great for this. Rice down below with some marinated protein and a courtesy vegetable up top. Think chicken thighs and sweet potato, sliced beef and broccoli, tofu and edamame, etc. To marinate just put your protein in a ziploc bag with equal parts olive oil, lemon juice and soya sauce.
Japanese curry is another nice easy one. Boil your protein with potatoes and carrots for 20mins, add the package of curry blocks, stir and let it sit for 10 mins. Serve it with rice or udon noodles. Pretty minimal effort and can be done in a large batch like chili
Dude. Talk to a doctor somehow, try telemedicine, a clinic, whatever it takes. Explain your situation to them, maybe they can hook you up with some samples. Anything but fucking with random shit off the street. Don’t become a fentanyl statistic
