In a large mixing bowl, combine the ground beef with finely chopped onion, minced garlic, cilantro, ground cumin, ground coriander, paprika, salt, and pepper.

Mix the ingredients until well combined, forming a slightly sticky mixture.

With wet hands, form the mixture into oval-shaped patties or skewers, about 1 inch thick.

Preheat the grill to medium-high heat, greasing grates with oil.

Place the koftas on the grill and cook for approximately 5 minutes on each side, or until they reach an internal temperature of 160°F.

In a separate bowl, mix Greek yogurt with fresh lemon juice and finely chopped dill or mint.

Season with salt and pepper to taste and allow to rest for at least 10 minutes before serving.

Once koftas are cooked, let them rest briefly before serving alongside the yogurt sauce.
