Chicken Tips with Peppers and Onions

My wife and I recently went on a short vacation. After we checked into our room, we decided on dinner. The front desk clerk suggested the local steak house. We decided to check it out. We both ordered beef tips, mine with onions and peppers, and my wife's with mushroom gravy. They were amazing. Extremely tender, lightly seasoned, with the onions and peppers cooked just right. The waitress said if we liked the beef tips we should try the chicken tips. The next day we both were really looking forward to those tips. When dinner time arrived, we went straight to the steak house. They were closed for the next three days.
This is my version.
Ingredients:
3 boneless skinless chicken breasts
1 large sweet onion
2 bell peppers
1 teaspoon Tuscan infused olive oil
1 teaspoon seasoning salt

Begin by think slicing the onions.  Add the olive oil to a preseasoned pan allow to grill about 10 minutes. While the onions are cooking, thinly sliced the peppers. Add the peppers to the skillet and continue to grill at a low temperature turning frequently.

Season the chicken with the seasoning salt and place the pieces on grill preheated to 300 degrees. Allow to grill until the internal temperature is 165 degrees. Remove and allow to rest about five minutes. Slice chicken into bite size pieces. Add chicken to peppers and onions. Mix well. Plate and enjoy.
