Here are some lasagna burgers I made
What you need: 4 cooked burger patties, 4 burger buns, some spaghetti sauce, and 4 cooked lasagna noodles and some mozzarella
First you want to toast the buns. These ones got a little burnt.
Place the burger patties on the burger buns you can put the mozzarella on top, or like I did you can place the cheese inside the burger before you cook it.
