Turkey Burger With Barbecued Red Onions

1 1/2 pounds ground turkey
Kosher salt and freshly ground black pepper to taste
4 sesame hamburger buns, toasted

For the onions:
4 1/2-inch-thick slices red onion
Jack Daniel's Sizzling Smokehouse Blend Grilling Sauce

Topping:
Monterey pepper jack cheese, sliced
Avocado, sliced (optional)

Chipotle mayonnaise:
1/2 cup mayonnaise
1 teaspoon sugar
1 tablespoon pureed chipotle in abodo sauce (from canned chipotles) or to taste
Juice of 1/2 lime

Preheat barbecue to a medium-high heat.

Combine the ground turkey with salt and pepper to taste, tossing gently. Shape into 4 patties about 3/4-inch thick. Coat the patties with a nonstick spray before grilling so they won't stick to the grill grate. Grill for about 5 minutes.

Meanwhile, grill the onions, brushing with the sauce. Grill the onions until soft, about 8 minutes. Turn often, brushing with additional sauce.

Top burgers with cheese after flipping; continue to grill the burgers for about another 4 to 5 minutes (until internal temperature registers 160 degrees).

For the mayonnaise: Blend all of the ingredients together in a small bowl and allow to sit for about 30 minutes before serving.

Serve the burgers with the chipotle mayonnaise, grilled onions and avocado slices (optional).

Serves 4.
