Makes 4 burgers
1 teaspoon olive oil
1 medium yellow onion, finely chopped
1 medium apple, peeled and grated
1 pound ground turkey thigh (ground turkey thigh stays moister than ground turkey breast; available at most supermarkets)
2 tablespoons Worcestershire sauce
Salt and pepper to taste
4 rolls, split and lightly toasted
Preheat oven to 450 F. Heat olive oil in a large sauté pan; add onion and slowly sauté until golden brown. (If the onion begins to stick to the pan, add small amounts of water a bit at a time.) Add grated apple and cook for another 3–5 minutes, or until soft. Transfer to a small bowl and cool thoroughly.
Combine ground turkey with onion-and-apple mixture and season with Worcestershire, salt and pepper. Divide into 4 equal parts and shape into burgers. Roast on a nonstick sheet pan for 20 minutes, or until the internal temperature is 160? F. Remove from oven and serve on rolls.
