Step 1:

• In a large mixing bowl, combine the ground lamb, chopped onion, minced garlic, ground cumin, ground coriander, paprika, salt, black pepper, and chopped parsley.
• Mix well until all ingredients are evenly distributed throughout the meat.

Step 2:

• Divide the lamb mixture into 4 equal portions.
• Shape each portion into a patty, about 1/2 inch thick.

Step 3:

• Preheat your grill or grill pan over medium-high heat.
• Place the lamb patties on the grill and cook for about 4-5 minutes on each side, or until they reach your desired level of doneness.

Step 4:

• While the patties are cooking, lightly toast the burger buns on the grill for about 1-2 minutes, until they are warm and slightly crispy.

Step 5:

• Assemble your lamb burgers by placing a lettuce leaf on the bottom half of each bun, followed by a lamb patty, tomato slices, and sliced red onion.
• Top with the remaining half of the bun.
