This Chicken and Veggie Teriyaki Skillet will have you passing up the store-bought teriyaki sauce for good! It's the perfect weeknight one-pot dinner for the whole family. It's loaded with bright colored bell peppers and chicken, covered in a tasty sauce that all cooks up in about 30 minutes and pairs well served over brown rice.
Heat 1 tablespoon of the olive oil in a large skillet over medium-high heat. Cook the onion and peppers, while stirring occasionally, until they soften and begin to brown, 7 to 9 minutes. Transfer to a bowl.
Meanwhile, pound the chicken with a tenderizer and dredge in the flour until well coated on all sides. After the veggies are removed from the pan, pour in the remaining 2 tablespoons of olive oil and add the chicken to the pan, still on medium-high. Cook until golden brown on both sides and cooked almost all the way through, about 5 minutes (depending on the thickness of the chicken).
Pour in the teriyaki sauce and scrape the brown bits off the bottom of the pan. Bring to a boil and cook for a couple of minutes until the sauce reduces down and begins to thicken.
Add back in the veggies and turn the heat down to low until the chicken is done all the way through (no longer pink in the middle). Top with a handful of cilantro (if using), and serve over brown rice or whole-grain ramen noodles.
