In large pan with high sides or dutch oven, heat oil. Brown chicken pieces, then remove from skillet and set aside.
In same pan, sauté onions, jalapeño, garlic and ginger over medium heat, being careful not to burn the garlic, about 2-3 minutes, until onions begin to soften. Add diced tomatoes and red pepper flakes. Saute a couple more minutes. Then add the peanut butter, chicken stock and tomato paste. Stir well to combine. Return the reserved chicken back to the pan, stir and simmer about 15 minutes.
