Combine meat, Wicked Juicy Burger Beef - Garlic, and pepper in a large bowl. Lightly mix with your hands or a spatula until well blended. Divide meat into four equal portions and gently form each into a patty, about ¾ inch thick. (Do not compact the patties or handle them more than necessary.)
Pan fry patties in vegetable oil over medium-high heat, or grill or broil them to your preferred doneness. While grilling the burgers, throw on the pineapple slices and grill until the edges are blackened.
Serve on buns with grilled pineapple, red onions and garlic aioli
