These tasty Prime Rib Quesadillas made with leftover prime rib are truly the ultimate in melty, cheesy, crispy quesadilla greatness! The tortillas are cooked until lightly golden, filled with a combination of the best melting cheeses, and tender pieces of perfectly medium-rare prime rib or steak!
Heat your large skillet or non-stick frying pan to medium heat with the olive oil. Spread the olive oil using a pastry brush or spatula to lightly coat the frying pan. *Add more oil as needed to keep your skillet lightly coated while cooking the additional quesadillas.
Combine your cheeses in a bowl or on the cutting board where you grated them. Warm the first tortilla in the heated frying pan then add a light layer of the combined cheeses, a handful portion of the cut prime rib, then top with the additional cheeses and the top tortilla.
Cook the quesadilla for about 2 minutes, or until the cheese is melted and the bottom is lightly golden browned.
Flip your quesadilla and cook the second side for an additional 2 minutes, or until the second tortilla is also lightly golden brown in color. Remove from heat and repeat with additional quesadillas.
