Variations & Tips
For a bit of spice, consider adding a pinch of red pepper flakes or a diced jalapeño to the mix. You can also swap out the mozzarella for cheddar or a blend of Italian cheeses for a different flavor profile. If you have some fresh vegetables on hand, like bell peppers or mushrooms, they can be sautéed with the beef for added texture and nutrition. For a creamier version, stir in a half cup of cream cheese or sour cream just before serving.
