For eating healthier on a budget I cook a whole chicken at the start of each week (make sure you get one that hasn't had salt added! So many whole chickens come with a 'solution' injected into them). I use a pressure cooker, but you could just roast it in the oven. I remove all the skin, then I remove the meat from the bone. The meat goes into a container and into the fridge and then I have a protein source for the week. Cooked chicken goes in veggie stir-fry (which I make by cooking veggies with just a touch of oil and then a tablespoon of hummus for flavor rather than soy sauce), on top of salad, or into a small amount of rice and veggies.
