Instructions

  1. MAKE SAUCE: Whisk sauce ingredients together in a small bowl. Set aside, allowing flavors to meld.
  2. MAKE VIDALIA: In a sauté pan over medium-low heat, heat butter and oil. Add sliced onion, sprinkle with brown sugar and simmer for approximately 20-30 minutes, stirring occasionally until caramelized. Set aside, keeping them warm.
  3. MAKE BURGERS: Meanwhile, preheat grill or a cast iron skillet to high. Divide the ground sirloin into 4 burgers. Season on both sides with salt and pepper, to taste. Grill or cook in the skillet for 3-4 minutes on each side for medium-rare doneness. During last minutes of cooking add caramelized onion to each burger, then 2 slices of cheese. Cover grill or pan for approximately 1 minute to melt cheese.
  4. ASSEMBLY: Spread Bistro sauce on bottom of the toasted buns. Place burgers on buns. Top with suggested toppings.
