Asian Turkey Burgers

In a medium bowl combine the turkey, mushrooms, and onion. Form into four 1/2-inch-thick patties. In a small bowl stir together the mayonnaise and hoisin sauce; set aside.

For a charcoal grill, place patties on the grill rack directly over medium coals. Grill, uncovered, for 10 to 13 minutes or until an instant-read thermometer inserted into side of each patty registers 165 degrees F, turning once halfway through grilling. (For a gas grill, preheat grill. Reduce heat to medium. Place patties on grill rack over heat. Cover and grill as above.)

For each serving, spread a bagel thin with one-fourth of the mayonnaise mixture. Top with a turkey burger and one-fourth of the napa cabbage.
