How to make the easiest Koobideh Kabobs!

Koobideh Kabob Recipe:
This is sister's Sameera and Sepeedeh's recipe
I made some changes in the recipe on the video!
8 Servings
Ingredients:
2 lb of the ground lamb or beef (my mom says it would be best if you have a mix of both types of meat)
2 onions grated and strained (mom says its really important to make sure there is no onion juice. Squeeze all the juice as much as possible before adding)
1 large egg (beaten)
5 medium tomatoes to be used for later when grilling or baking
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon red pepper tablespoon (optional)
1/2 teaspoon garlic powder (optional, mom adds it in sometimes. Also if you wanna add fresh garlic, ground 2 cloves into meat mixture.)
Directions:
Mix meat, onions, egg, salt and pepper(s) wellz Make sure to massage it throughly. Leave in the refrigerator overnight (or for several hours but its best to leave it for longer).
Press the meat around long, thick metal skewers. This is the difficult part. Make sure not to put too much meat on each skewer. It's taken lots of practice for my mom to perfect how much meat to put on each one. Make sure the skewers are thick as well. If they're too thin, the meat won't hold. Thread whole tomatoes on another skewer. Barbeque each side for about five minutes, turning frequently. If skewers are not available or barbequing is not possible, kabab-e koobideh can be shaped into long, thin portions on aluminum foil and grilled at high temperature in the oven.
Serve with hot Saffron rice or on middle-eastern bread. If serving with rice, add a little sumac on top.
