Eating Healthier

In the mindset of being healthier, I've been consciously thinking about the food I eat.  (No, I don't keep a food log - hate those!)  But I realized that I eat pasta or rice almost every day at lunch.  And if not that, then a sandwich.  I always have fruits or vegetables as well.  But I'm thinking of trying to change that and instead of having grainy starches, to have some starchy vegetables.  I want to continue to eat other non-starchy vegetables too.  But I need some advice.  And oh yea, it needs to be easy!  Making lunch with the kids isn't always the time for fancy foods.  So if anyone has any suggestions, or places to look, I will greatly appreciate it!
