Kebab Koobideh (Ground Meat Kebabs)

This dish is a common Iranian food, the "meatloaf" of Persian culture. Best if cooked on a grill and served with rice or pita bread. Noosh e joon!

Ingredients
2 pounds ground meat (lamb or turkey)                  
1 medium Onion, grated
2 tsp salt, 1 tsp black pepper
2 Tbsp sumac ( a middle eastern spice)
1/2 tsp turmeric
1/2 teaspoon baking soda
4 medium tomatoes
2 Tbsp melted butter
2 limes, juiced

Method
Mix the meat, onion, spices and baking soda with hands for ten minutes like bread dough until it develops a pasty consistency. In separate bowl, mix the lime juice and butter. Form meat paste into long, sausage like shapes or meatballs. Fire up the grill. Brush shaped meat and tomatoes with lime-butter sauce and grill for 8-10 minutes. Remove from heat and cover with foil for 10 minutes so that the meat retains its juices. Serve.
