Add onion and green pepper and saute for about 5 minutes.
While your veggies are sauteing cut up your plant-based chickens tenders. I cut mine in thirds and fourths, lengthwise. Depending how wide they are. Then I cut all of those slices in half.
Add the cut up meatless chicken pieces and cook about 10 more minutes and you will get a little browning on this chicken. This is good.
Add all the other ingredients to the pan and cook for 15 minutes or until the sauce has become thick and caramelized. Imagine it being on a bun so it needs to be thick.
