Roasted Balsamic Onions: Preheat oven to 450 degrees, and lightly coat a shallow baking pan with cooking spray. Arrange the onions in one layer in the pan and roast in the middle of the oven, stirring occasionally, until golden brown and just tender, about 15 minutes. Drizzle vinegar over the onion and roast until most of the vinegar is evaporated, about 3 minutes. Season with salt and pepper, cover and keep warm.

Grilled Peaches: Cut peaches in half and remove the pit. Brush lightly with olive oil. Heat grill to medium-low heat. Place peaches on grill; cover grill and cook until charred and softened, about 4-5 minutes per side. Set aside and keep warm.

Burgers: Divide meat into 4 and form patties. Heat grill to medium heat. Season patties with salt and pepper to taste. Grill burgers to desired doneness.

Toast buns on grill until toasty with clear grill marks.

Assemble: Bun, Garlic Spread, radicchio and arugula, beef patty, cheese, peaches, onion and top bun.
These will be the talk of your next barbecue! Enjoy this taste of summer!
