Our new favorite thing to grill is a turkey London broil. Yummy and good for you! We usually top it with a teriyaki sauce.
Oh, and veggies on the grill (red peppers, zucchini, onions, mushrooms, etc.) are great. We usually kabob them just because they are easy to deal with that way. I light brush of olive oil and s&p is usually all we do for those.
