First you want to make your sauce. In a small bowl, add bbq sauce, onion powder, garlic powder and tomato paste. Mix well until everything is combined. Set aside.
In large sauté pan, add some olive oil over medium heat. Add cut up chicken breast to pan. Season with some salt and pepper. Cook for about 8-10 minutes until each piece is cooked.
Once your chicken is done, add your sauce mixture to pan and mix together until each piece of chicken is coated. Turn heat down to low and cook for another 3-5 minutes covered.
Prepare your lettuce leaves. Make sure they are large enough.
When your chicken is done, spoon bbq chicken onto lettuce leaf. Add pineapple and red onions on top.
Enjoy!
