Grilled pineapple adds a sweet balance to these savory burgers. We serve them bunless but you can turn them into sandwiches as well. (Add points for the bun.)

* 1/4 cup scallion(s), sliced
* 3 Tbsp teriyaki sauce

* 1/2 medium vidalia onion(s), cut into four 1/4-inch-thick rounds
* 4 sprays cooking spray
* 1/4 cup cilantro, fresh, chopped

Instructions

* Preheat grill or grill pan to medium-high.

* In a medium bowl, combine beef, scallions, teriyaki sauce, ginger and garlic until thoroughly mixed; form into four 3/4-inch-thick patties.

* Off heat, lightly coat burgers, pineapple and onion with cooking spray; place on grill. (Never spray cooking spray onto an open flame.)

* Grill pineapple, turning once, until lightly charred, about 4 minutes; remove from grill and cover to keep warm. Grill burgers and onions, turning once, until burgers are desired degree of doneness and onions are lightly charred and tender, about 7 to 9 minutes.
