Ingredients

  • 1/2 cup sun-dried tomatoes, packed without oil
  • 1/4 cup minced shallots
  • 2 tablespoons Dijon mustard
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon paprika
  • 1/2 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 1/2 pounds ground sirloin
  • 1 garlic clove, minced
  • Cooking spray
  • 6 (2-ounce) Kaiser rolls, split
  • 6 (1/8-inch-thick) red onion slices

Method

  • Place tomatoes in a bowl; cover with boiling water. Let stand 30 minutes or until soft. Drain and finely chop.
  • Prepare grill.
  • Combine tomatoes, shallots, and next 7 ingredients (through garlic). Divide mixture into 6 equal portions, shaping each into a 1/2-inch-thick patty.
  • Place patties on a grill rack coated with cooking spray; grill 5 minutes on each side or until a thermometer registers 160°. Remove from grill; let stand 5 minutes.
