Cut the chicken fillet into 4 parts, salt, pepper, fry in 3 tbsp. l. olive oil on both sides until golden brown, 8 minutes. Blanch tomatoes, chili peppers for 2 minutes, remove the stalks, peel, chop in a blender. Add wine, stir. Pour the fried chicken pieces with the resulting sauce and simmer under the lid for 8-10 minutes, until tender. Heat the tortillas in a separate pan in the remaining olive oil. Serve fillets on tortillas, garnished with basil. Serve the rest of the sauce separately.
