Prepare Chicken - In a food processor, make a paste of onion, chili peppers, turmeric, coriander, and laos. In a large skillet, add coconut milk, bay leaf, lemongrass, and stir in the spice paste. Add the chicken pieces and bring to a boil. Reduce heat to medium and simmer until the chicken is tender, about 25 minutes. Remove from heat and transfer chicken to paper towels to remove any excess marinade.
