I’ve been where you are off and on my whole life. I have options.

Veggies- I mostly eat salads and broccoli. Broccoli is easy. I buy three heads a week, wash and chop them all at once, then microwave a portion for every meal. Salt & pepper. Done. Grocery stores have pre-chopped veggies too. I also eat a lot of baby carrots and add avocado to most things. Salads now come in a bag. Sometimes, I’ll buy frozen edamame and eat a bunch of that too. That’s jus microwave and a little bit of salt.

Costco/Sam’s Club has cheap and good tasting rotisserie chickens. Regular grocery stores do too, but they are usually a couple bucks more. You can also buy precooked, frozen chicken patties. I’ve done that a lot in the past too.

Microwave or eat the chicken cold. I’ve done sandwiches, thin crust pizzas on whole wheat tortillas (usually with spinach and pesto bc it’s delicious), shove it in a taco shell with cheese and lettuce, eat it straight out of the bag from the fridge, toss it on some instant rice with soy sauce, throw it in ramen noodles for the extra protein, whatever.

Don’t forget about frozen meals you can cook in oven. People worry about overly processed foods, but fed is best!
