**Pressure cooker instructions - Lightly spray with cooking oil or drizzle a little oil in the bottom of the pressure cooker. Follow step one, except place the trimmed thighs in the bottom of the pressure cooker. Do steps 2 and 3. Lock the lid on and make sure the vent on top is turned to closed. Next, manually set the pressure cooker for 20 minutes (25 minutes if the thighs are frozen). Sauté the mushrooms in 1 Tablespoon of butter in a skillet on the stovetop. Release the steam from the vent when the timer goes off. Remove lid. Use 2 forks to break up the chicken. Add in the sauteed mushrooms. Do step 6.
