I've been eating less of those microwaved meals (even if they are healthy) and feel more energized and have lost weight as a result. I try to buy foods I really enjoy that are good for me too. If I buy something very healthy that I hate, I won't eat it or I'll eat a bite and waste the rest. I really enjoy berries, baby carrots, things like that... and if I buy the veggies I hate, it'll just be a waste! Try to stick with things you will look forward to eating.
Even with dollar menu's around, I find that most of my meals at home are still cheaper. As a college student, I can't afford to go out to eat all the time and I enjoy eating at home. I like to buy some good meat and grill it on my George Foreman grill, buy things to make healthy sandwiches, stuff like that. Soups are good too... just make sure the kind you get isn't too high in sodium like some are. I also enjoy eating tuna and making fresh salads with chunks of turkey in it and a light dressing.
