Lettuce wraps. Grilled/baked/broiled chicken breast meat and veggies cut up, mixed with a little dressing and wrapped in lettuce leaves.
We used to make a simple salad that was delicious.
Small cut cauliflower and broccoli; tiny whole tomatoes (mostly color, so red peppers or pimento would do better); small black olives; matchsticked water chestnuts and canned mushrooms. Mix in a bowl pour Italian dressing over, and let sit at least overnight. You could use canned tuna or salmon for protein – grilled, even better. Would make a great filling for lettuce wraps or just as a salad.
Stir fry, if you have a variety of veggies.
