Something fun to grill - Egyptian Kofta

This is the hamburger of Egypt or even possibly of the middle east.  I first had these at this great hole-in-the-wall Egyptian restaurant in Allston called Azama Grill  .  They mold the meat around a skewer, but I decided to skip the wooden skewer and just made the same long shape... kind of a like a sausage or a long skinny hamburger.

Ingredients:
1 yellow onion, quartered
1/4 - 1/2 purple onion, quartered
4 garlic cloves, roughly chopped
1 tablespoon fine sea salt
1 teaspoon ground cumin
1 teaspoon freshly ground pepper
1 cup finely chopped flat leaf parsley
2 lbs. ground beef or lamb or a combination

1. Put the onions and garlic in a food processor and process until finely chopped.

2. To the onion mixture in the food processor add the cumin, salt, pepper, chopped parsley and the ground meat. Process until the meat and the onions and parsley are thoroughly combined and the blades are running smoothly.

3. Shape into sausage logs and arrange on a sheet pan (makes approximately 9 koftas) and refrigerate until ready to grill (from 4-10 hours).

4. Brush koftas with olive oil and cook on a hot grill until the internal temperature reaches 160 degrees, turning as needed.

These can be served with tahini sauce and lettuce or just a squeeze of lemon juice.
