Preheat oven to 400° spray muffin cups with cooking spray, place celery, onions, red and green peppers in a food processor and pulse a couple times untill finely chopped but not liquefild. put that in a bowl and mix in your turkey or meat, the rice, egg, worcestershire sauce and dijon mustard untill thoroughly combined.

Fill each cup about 3/4 of the way. Top each of them of with the barbecue sauce, about a teaspoon each would do. Bake untill juices run clear, about 25 minutes. The internal temp of the muffin should be 160°
