Use immersion circulator to heat water to 145 degrees
Cook at 145 degrees for 2 hours.
Remove bags from water and then remove chicken from bags. Note there will be a lot of liquid! Keep that, bring to a simmer, reduce to your thickness liking.
Heat remaining 2 tablespoons of olive oil in a large skillet over medium high heat. Add chicken to skillet and cook until browned on each side, about 2-3 minutes per side.
Oven Method
Preheat oven to 400°F
Line a cookie sheet with tin foil.
Sperate chicken from excess marinade and space out evenly on prepared cookie sheet.
Bake for 20 minutes or until internal temperature reaches 165°F.
You can use the excess marinade to make a sauce. Add to a small pot or frying pan, bring to a low simmer, being careful not to scorch the yogurt. Reduced by half or until to your thickness. Adjusting seasoning as needed. A teaspoon of harissa is quite delicious if you have it on hand.
Serve with sides of grain like couscous or salad, using the marinade sauce as dressing.
