Preheat oven to 425°F
Add the onion, garlic, bell pepper & parsley to a food processor and pulse until finely minced
Add the ground chicken to a bowl along with the onion mixture, tomato paste, and spices (sumac, Aleppo pepper, smoked paprika, cumin, turmeric, salt & pepper). Drizzle with olive oil
Mix really well, and transfer to a sheet pan and spread evenly across the bottom
Smooth the edges, then cut long vertical lines through the chicken to form individual kebabs with space between them. Add little indentations with the back of a spatula
Bake for 18-20 mins, then move to the top rack and broil for 2-3 mins to get some color
