Wash the Chicken and cut them to pieces. Neither too big nor too small, just good enough that they can go through the skewer and have enough meat to hold on to.
Add Peanut Butter to the Chicken.
Add Ginger paste, cumin Powder, Red chili powder, Turmeric Powder, Red chili flakes, salt, Brown sugar and Tandoori powder to the Chicken.
Add in Vinegar and Soy sauce and mix well. Cover and refrigerate for 45 minutes to an hour.
Put in the skewers along with onions and Bell Peppers.
Preheat the oven to 400F. Baste the kebabs with some butter or Oil.
Place the Kebabs in the oven for 25-30 minutes. Keep rotating them every 5-7 minutes.
If you like them well done, then leave for an extra 2 minutes on broil.
