1. Heat oil in a large deep skillet. Add the small chunks of tomatoes and cook, uncovered, on a medium to high flame for approximately 20-30 minutes or until most of the liquid evaporates.
2. Add chicken strips or wings and cook for an additional 20-30 minutes, flipping chicken midway to ensure that the chicken is fully cooked.
3. Raise the flame for an additional 3-5 minutes to caramelize tomatoes to your preference.
