1 pound ground turkey
2 egg whites
1 small yellow onion, chopped (about 1/2 cup)
1/4 cup dijon mustard
3 tablespoons chopped fresh tarragon or 2 teaspoons dried tarragon
3 tablespoons whole-wheat bread crumbs
1/4 teaspoon black pepper
4 whole-wheat sandwich buns
4 lettuce leaves
1 medium tomato, thinly sliced

Directions
Heat a charcoal grill until coals form white ash, or preheat the broiler.

In a large bowl, combine turkey, egg whites, onion, mustard, tarragon, bread crumbs, and pepper. Mix well. Shape turkey mixture into 4 even patties.

Grill or broil burgers 4 inches from heat, turning once, until browned and cooked through, about 15 minutes. Transfer turkey burgers to a plate.

Split buns and place them on serving plates. Place a burger on bottom half; top each burger with lettuce and tomato. Place tops over burgers and serve.
