Sauté celery, turnip, onion, and serranos in a drizzle of avocado oil on medium heat for 2-3 minutes
Add chicken, spices down, to the pan, moving the veggie mix to the side so the chicken touches the skillet. Cook until browned on the bottom, about 3-4 minutes.
Flip the chicken and add the Yai Thai's yellow Thai curry sauce. Fill the jar up halfway with water and add to pan.
Simmer on medium-low for 20-25 minutes or until chicken is cooked through
Great served over rice, cauliflower rice, swiss chard or plain as a soup.
