Pat the chicken breast dry with a paper towel and cut it into bite-sized 1-inch cubes.
Heat the avocado oil in a large skillet over medium-high heat until it begins to shimmer.
Add the chicken cubes to the skillet and season them evenly with the sea salt and black pepper.
Sear the chicken for 5 to 6 minutes, stirring occasionally, until the pieces are golden brown and cooked through.
Remove the cooked chicken from the skillet and set it aside on a plate.
In the same skillet, add the broccoli florets, sliced red bell peppers, and diced zucchini.
Sauté the vegetables for 4 to 5 minutes until they are bright in color and reached a crisp-tender texture.
Stir in the minced garlic and grated fresh ginger, cooking for about 1 minute until the mixture becomes highly fragrant.
Return the chicken and any accumulated juices to the skillet and pour in the coconut aminos.
Toss all ingredients together for 1 to 2 minutes until the chicken and vegetables are well-coated and glazed before serving.
