  • 1 tablespoon Gold’s horseradish
  • 1 tablespoon ketchup
  • 1 large red onion, cut into 1/4-inch thick rings
  • 4 (1/4-inch thick) cored round slices fresh pineapple

Instruction

  • In a small bowl, combine mayonnaise, horseradish, and ketchup and set aside. Preheat grill to high heat. Rub onion and pineapple slices with olive oil and grill 3 to 4 minutes per side or until tender, but still holding their shape, then set aside. Meanwhile, season burger patties with salt and pepper and grill for 8 minutes per side for medium rare, or about 12 minutes per side for medium, or longer depending on desired doneness. Let rest 4 minutes before assembling burgers. Divide horseradish mayonnaise between 4 bottom buns. Top with lettuce, burger, grilled onion and pineapple. Add top bun and serve immediately.
