Cheeseburger Quesadillas

Ingredients

• 1/2 pound ground beef
• 1/2 red onion, diced
• 1 clove garlic, minced
• 1 pinch salt
• 1 cup shredded Cheddar cheese, divided
• 1/4 cup shredded mozzarella cheese
• 1 tablespoon milk
• 1 tablespoon butter, divided
• 2 (12 inch) flour tortillas
• 2 tablespoons Thousand Island dressing, divided
• 1 romaine lettuce heart, sliced
• 1 tomato, sliced
• 1/2 red onion, sliced

Directions

Combine beef, diced onion, and garlic in a large skillet; cook and stir until beef is no longer pink, 5 to 8 minutes. Season with salt.

Transfer beef to a saucepan over low heat. Add 3/4 cup Cheddar cheese, mozzarella cheese, and milk. Cook and stir until cheese is melted, 3 to 5 minutes.

Melt half the butter in a large skillet over medium heat. Cook 1 tortilla until golden brown on the bottom, about 3 minutes. Flip tortilla and spread with 1 tablespoon dressing. Spoon half of the beef mixture over the tortilla; fold in half. Cook until tortilla is golden brown, 1 to 2 minutes per side. Transfer to a serving plate. Repeat with second tortilla.

Sprinkle remaining 1/4 cup Cheddar cheese over tortillas. Let cool, about 5 minutes. Cut into wedges and serve with lettuce, tomato, and sliced onion.
