These are a family favorite I made the other night and since it's summer and people are grilling, figured I'd share!  You could use ground chicken or beef too, I suppose.
 
20 oz. pkg. ground turkey                    1/2 cup bread crumbs
1/3 cup finely chopped bell pepper        2 tbsp. finely chopped green onions
1 tsp. chili powder                                1 tsp. ground cumin
1/2 tsp. salt                                        pepper to taste
1 tbsp. lime juice
 
Texas Toast or burger buns
 
Stir all burger ingred. together and form 4-5 patties.  Grill over medium heat.  Serve w/ salsa, avocadoes, etc.
