In a large bowl, combine ground beef (or lamb), minced garlic, chopped parsley, cumin, paprika, salt, and black pepper. Mix well until all ingredients are evenly combined.

Shape the Patties

Divide the mixture into 4 equal portions and shape each portion into a patty.

Cook the Patties

Preheat a grill or skillet over medium-high heat. Cook the patties for about 4-5 minutes on each side, or until they reach your desired doneness. Add a slice of cheese on top of each patty during the last minute of cooking to melt.

Make the Garlic Aioli

In a small bowl, combine mayonnaise, minced garlic, lemon juice, salt, and pepper to taste. Mix until smooth.

Assemble the Burgers

To assemble, spread garlic aioli on the bottom half of each burger bun, add lettuce, a cooked patty with melted cheese, tomato slices, onion slices, and top with the other half of the bun.
