Cook ground chicken in a large skillet on the stove top until cooked through.
Add the olive oil, soy sauce, teriyaki sauce, rice wine vinegar, mushrooms, onion, green onion, water chestnuts, ginger, garlic, salt and pepper, and garlic salt until the onions are tender and clear.
Continue stirring until everything is fully incorporated and warmed through.
Remove from heat and serve in lettuce leaves.
Notes
If you can't find ground chicken, ground turkey or ground beef are great substitutes.
If you don't like lettuce, you can also wrap the meat mixture in a tortilla or even a cabbage leaf. It would also be delicious served on a salad.
