Step 1
In a bowl combine bison, onion, salt, pepper and garlic powder. Mix well, if mixture appears too dry, add some cold water. Form slider patties using a measuring tablespoon, about 4 Tablespoons for each patty. Place on parchment paper.
Step 2
In a small skillet, sauté onion in 1 Tablespoon olive oil, until soft.
Step 3
Preheat a gas grill to medium-high heat. Grill burgers for 1-2 minutes per side, depending on desired doneness.
Step 4
Add cheese on top of each mini burger right after you remove them from the grill so it can melt.
Step 5
Lightly toast slider buns and assemble the burgers, adding lettuce, sautéed onion, HEINZ mustard and any additional toppings of your choice.
