Start by cutting your chicken breasts into bite-sized cubes. Next, seed and slice your red bell pepper into strips. Mince the garlic and chop the ginger finely to release their fragrant oils.
In a bowl, combine the cubed chicken with 1 tablespoon of soy sauce, 1 tablespoon of white vinegar, and 1 tablespoon of coconut palm sugar. Add the freshly ground black pepper and mix well. Let the chicken marinate for at least 15 minutes to absorb the flavors.
In a large skillet or wok, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is hot, add the marinated chicken to the pan in a single layer. Cook for about 5-7 minutes, stirring occasionally, until the chicken is browned on all sides.
Once the chicken is cooked through, add the minced garlic and chopped ginger to the skillet. Sauté for about 1 minute, or until fragrant. Be careful not to burn the garlic, as it can turn bitter.
Add the red bell pepper strips to the skillet and stir to combine. Cook for an additional 3-4 minutes, allowing the peppers to soften slightly but still retain some crunch.
Pour in the remaining soy sauce and white vinegar, stirring to coat the chicken and peppers evenly. Let everything simmer for another 2-3 minutes, allowing the flavors to meld together.
Once everything is well combined and heated through, remove the skillet from the heat. Serve your One Pot Black Pepper Chicken over steamed rice or noodles, and enjoy the deliciousness!
