Time 45m

Number Of Ingredients 14

1 small red onion, thinly sliced
1 pound ground turkey (preferably dark meat)
4 teaspoons minced fresh ginger (from a 1-inch piece)
2 teaspoons minced garlic (from 1 to 2 cloves)
2 teaspoons reduced-sodium soy sauce
2 teaspoons toasted sesame oil
Kosher salt
Vegetable oil, for grill
8 thin slices pineapple (from 1/2 cored pineapple)
4 King's Hawaiian Sweet hamburger buns or brioche buns
2 ounces Havarti cheese, thinly sliced
1/3 cup mayonnaise
1/2 jalapeño or serrano pepper, chopped (ribs and seeds removed for less heat, if desired)
Green-leaf lettuce, for serving

Steps:

Preheat grill to high (see cook's note if using charcoal). Cover onion with cold water and let stand 10 minutes; drain and pat dry. Mix together turkey, ginger, garlic, soy sauce, and sesame oil. Shape into four 4-ounce patties, then flatten each to 1 inch thick and season with salt. (Patties can be made a few hours ahead and refrigerated.)
Brush grates with vegetable oil. Grill pineapple until lightly charred on both sides and softened, 4 to 5 minutes. If desired, grill split sides of buns until lightly charred, about 30 seconds.
Grill patties until slightly charred and just cooked through, 6 to 8 minutes a side. In last minute of cooking, top each patty with cheese, cover grill, and let melt.
Stir together mayonnaise and jalapeño. Spread buns with mayonnaise mixture and use to sandwich patties, pineapple, lettuce, and onion.
