1/4 cup coarse-grained mustard
1/4 teaspoon freshly ground pepper
2 tablespoons honey
2 teaspoons canola oil
1 pound ground turkey breast
4 whole-wheat hamburger rolls, split and toasted
1/4 teaspoon salt
Lettuce, tomato slices and red onion slices, for garnish
Oil and heat grill to 350.
Whisk mustard and honey in a small bowl until smooth.
Combine turkey, 3 tablespoons of the mustard mixture, salt and pepper in a bowl; mix well. Form into four 1-inch-thick burgers.
Lightly brush the burgers on both sides with oil. Grill until no pink remains in center, 5 to 7 minutes per side. Brush the burgers with the remaining mustard mixture. Serve on rolls with lettuce, tomato and onion slices.
