Ingredients:

Salsa
2 tablespoons olive oil
2 tablespoons fresh lemon juice
1 tablespoon honey
2 beets, boiled, peeled, cut into 1/3-inch cubes
1 large orange, peel and pith cut away, flesh cut into 1/3-inch cubes
1 cup chopped red onion
1/4 cup chopped pitted green Greek olives

Burgers
1 large shallot, minced
2 tablespoons chopped fresh cilantro
1 jalapeño chili, seeded, minced
1 garlic clove, minced
1 1/4 teaspoons salt
3/4 teaspoon ground black pepper
1/2 teaspoon paprika
1/2 teaspoon ground cumin
1 3/4 pounds ground lamb

Nonstick vegetable oil spray
4 large cracked-wheat hamburger buns, split horizontally
1 1/3 cups thinly sliced Bibb lettuce
Mayonnaise

Preparation

For salsa: Whisk first 3 ingredients in medium bowl to blend. Mix in next 4 ingredients. Season salsa to taste with salt and pepper.

For burgers: Stir shallot, cilantro, jalapeño, garlic, salt, black pepper, paprika, and cumin in large bowl to blend. Add lamb and mix gently to combine. Shape mixture into four 1/2-inch-thick patties. Arrange on small baking sheet.

Spray grill rack with nonstick spray and prepare barbecue (medium-high heat). Grill buns, cut side down, until golden, about 2 minutes; transfer to work surface. Place lettuce and large spoonful of salsa on each bun bottom. Grill burgers until slightly charred and cooked to desired doneness, about 4 minutes per side for medium-rare. Place 1 burger on each bun. Top each with mayonnaise and bun top. Serve with remaining salsa.
