For glaze, in a small saucepan stir together orange marmalade and the 1/2 teaspoon soy sauce. Cook and stir over low heat just until marmalade is melted. Cover and set aside.
In a medium bowl combine bread crumbs, egg product, peanuts, the remaining soy sauce, ginger, and pepper. Add ground turkey; mix well. Form turkey mixture into two 1/2-inch-thick patties.
For a charcoal grill, place patties on the greased rack of an uncovered grill directly over medium coals. Grill for 11 to 13 minutes or until patties are done (165 degree F), turning once and brushing with glaze the last 1 to 2 minutes of grilling.
Serve the burgers on buns; top with lettuce leaves. Makes 2 servings.
For a gas grill, preheat grill. Reduce heat to medium. Place patties on a greased grill rack directly over heat. Cover and grill as above.
Place patties on the greased unheated rack of a broiler pan. Broil 4 to 5 inches from the heat for 11 to 13 minutes, turning once and brushing with glaze the last 1 to 2 minutes of broiling.
Prepare as above, except use the 1 teaspoon soy sauce (in step 1) and form turkey mixture into four 1/2-inch-thick patties (in step 2).
