In a large Ziplock bag, add the diced chicken, teriyaki sauce and 2 Tablespoons of olive oil.
Seal the bag, moving everything around until it is fully covered with sauce, and let marinate in the refrigerator for at least 30 minutes, if possible.
If you’re short on time, you can add chicken, sauce, and olive oil to bag and just toss to coat.
Preheat the oven to 375°F. Line a large baking pan with parchment paper.
Add pineapple chunks, red bell pepper, and stir fry vegetables to the baking pan.
