Cooking ideas?

Me and my man are moving out this weekend, we eat out a lot and I know we're going to have to buy groceries in order to save money, also I want to be healthy. I know he does to but we have really bad habits of eating out and just overall eating bad stuff. How can I be motivated to eat better? I've tried the healthy cooking but I always fall back and have all this veggies and fruit go to waste. :/
