Peel and finely grate the yellow onions. Place the grated onions in a fine mesh sieve and press down to extract the juice. Discard the solid remains.

In a large mixing bowl, combine the ground beef or lamb with the grated onion juice. Mix thoroughly to ensure the onion flavor is evenly distributed.

Add the flavorless oil, dissolved saffron, lemon juice, pepper, and salt to the meat mixture. Mix well to combine.

Cover the bowl and let the meat marinate for at least 2 hours, or preferably overnight in the refrigerator. This allows the flavors to meld and the saffron to impart its rich color and aroma.

Preheat your grill to medium-high heat. If using skewers, soak them in water for about 30 minutes to prevent them from burning.

Take a portion of the marinated meat and shape it onto skewers or form it into kabob shapes. Make sure the meat is evenly distributed to ensure even cooking.

Place the kabobs on the preheated grill and cook for about 10-15 minutes, turning occasionally, until they are cooked to your desired level of doneness.

Optionally, baste the kabobs with any remaining marinade during grilling for added flavor.

Ensure the kabobs are thoroughly cooked. The internal temperature should reach at least 160°F (71°C) for ground beef or lamb.

Adjust the seasoning if needed, adding more salt and pepper according to your taste.

Remove the kabobs from the grill and serve them hot. They can be enjoyed on their own, with rice, or wrapped in flatbreads.
