Begin by heating a large skillet over medium heat. Add the ground beef, breaking it apart with a spatula, and cook for about 5-7 minutes until it’s browned and no longer pink. Ensure to drain any excess fat from the skillet.

In the same skillet with the cooked beef, add sliced onions. Stir often as they cook over medium heat for around 10-15 minutes, until they soften and turn a beautiful golden brown.

Once the onions are caramelized, stir in gluten-free soy sauce and your choice of cheese. Cook the mixture for an additional 3-5 minutes, allowing the cheese to melt thoroughly.

To assemble your Sloppy Joes, toast your gluten-free buns lightly in the same skillet or an oven until they are golden (about 2-3 minutes). Spoon a generous amount of the beef mixture onto each bun.
