Take your chicken breast in a cutting board. First of all dice them and then cut very thin lines from your chicken.
Add 1/2 tbsp. tomato paste, 1/2 tbsp. pepper paste, 1 full tbsp. yogurt, 4-5 tbsp. vegetable oil, salt, 2 tsp. garlic powder in a large bowl and whisk until combined.
Add 2 tsp. thyme, 1 tsp. red pepper flakes, 1/2 tsp. ground red pepper, 1/2 tsp. ground red pepper, 1/2 tsp. black pepper, 1/2 tsp. ground cumin to the bowl and stir well.
Put your chicken breasts in the mixture, mix well until fully covered, put a stretch film on the bowl and let it rest about 2-3 hours in your fridge.
Heat your teflon or ceramic pan in a medium heat.
Cook your chicken doner until fully fried while stirring occasionally.
