Whisk together sauce ingredients until well combined. If you use a firmer peanut butter you may need to microwave the mixture for 30-60 seconds in order to melt it and ensure everything is well-mixed.
Heat 2 Tablespoons peanut oil in a frying pan. Once hot, add ground chicken, onion and minced garlic.
Cook until chicken browns and the onions are translucent, cook for 5 to 10 minutes.
Add the peppers and water chestnuts and cook about 5 minutes or until peppers are slightly soft.
Add the sauce and simmer on low heat until the chicken and veggies are evenly coated and everything is heated through.
Serve in lettuce leaves, on top of your favorite Asian salad, or over noodles or rice!

Notes
Ingredient Substitutions
Ground chicken: Finely diced chicken breasts are a great substitute for ground chicken!
Peanut Oil: Any oil can be used here if you don't keep peanut on hand or if you have a peanut allergy. I recommend olive oil or avocado oil!
Soy Sauce: If you have a soy allergy you can substitute coconut aminos for the soy sauce.
Peanut Butter: If you have a peanut allergy any nut or seed butter could work here, but peanut butter definitely gives the best results!
StoreStore any leftover lettuce wrap filling in an airtight in the refrigerator for up to 5 days. Store leftover lettuce separately in the refrigerator, because storing them together will make the lettuce soggy.FreezeFreeze the filling in an airtight container for up to 2 months.
