Cooking for my boyfriend

I've recently moved in with my boyfriend and have taken over cooking. He's decided that he wants to lose weight, it's great. He's super tall so I'm trying to find recipes for 500 calories lunches and dinners for him.What we keep in the house is usually,Chicken (breast, wings, thighs) Fish usually tilapiaBroccoli Carrots Roma tomatoes Potatoes Spinach Brussel sprouts OnionsWhite riceHe doesn't like brown rice nor does he want to eat pasta. My problem is that I got so accustomed to make myself very low calorie and small amounts due to the fact that I'm a short female.I just want to find around 500 calorie meals that'd he'd be full from. via /r/food http://ift.tt/2tJgB2u
