In a large skillet over medium heat, add a drizzle of olive oil and gently sauté thinly sliced onions. Stir frequently, allowing them to cook for about 10-15 minutes until soft and golden brown.

Once the onions are caramelized, push them to the side and add the ground beef into the open space. Cook on medium-high heat for about 5-7 minutes, or until browned. Mix the onions back in and drain excess fat.

Stir in the gluten-free soy sauce along with garlic powder and onion powder. Cook for an additional 2-3 minutes on medium heat to meld flavors.

Toast your burger buns until golden brown. Spoon the beef mixture onto the toasted buns, heaping the caramelized onions on top. Add slices of cheese and let them melt.

Serve warm, paired with crispy fries or a salad.
