1 lb ground turkey
1 egg, slightly beaten
5 oz frozen spinach (about half of a bag), defrosted
3/4 cup feta cheese
1 tsp salt + pinch of pepper
Mix together all ingredients with your hands and form four medium sized patties. Cook patties in a greased skillet for about 6 minutes per side, or until meat is completely cooked. Serve on toasted buns with extra feta, hot sauce, sliced onion, lettuce and ketchup and mustard.
