Mushroom bun burger

Stuff the mushrooms with mozzarella cheese and put them in the air fryer.

Heat a frying pan and press your thumb into the middle of any pattie before cooking (to ensure the middle is cooked evenly.

Once both sides are cooked, place the cheese on top and let them sit in the pan for 1 min.

Place the pattie between the two mushrooms and construct the burger the way you like it.
