1Heat a pan over medium heat and add the chopped onion and minced garlic. Cook until the onion is translucent.
Add the minced meat to the pan and cook until browned. Season with salt and pepper to taste.
In a separate pan, cook the sliced mushrooms until they are tender and any liquid has evaporated.
Combine the cooked mushrooms with the minced meat mixture and stir well.
Toast the burger buns lightly in a toaster or on a pan.
Assemble the burgers by placing a leaf of lettuce on the bottom half of each bun, followed by a generous portion of the mince and mushroom mixture.
Top each burger with a slice of cheese and the top half of the bun.
Serve immediately and enjoy your Mince and Mushroom Burger!
