Prepare the eggplant by cutting it into 1-inch cubes and lightly sprinkling with sea salt; let sit for 10 minutes then pat dry with a paper towel to remove excess moisture.
Slice the chicken breast into thin, bite-sized strips and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken strips to the pan and sear until golden brown and fully cooked through, approximately 5-6 minutes, then remove the chicken and set aside.
In the same pan, add the eggplant cubes and sliced bell peppers, sautéing for 6-8 minutes until the eggplant becomes tender and silky.
Stir in the minced garlic and grated fresh ginger, cooking for about 1 minute until highly fragrant.
Return the cooked chicken to the pan and pour in the coconut aminos and toasted sesame oil.
Toss all ingredients together for 2 minutes over heat until the sauce thickens slightly and coats the chicken and vegetables.
Garnish the dish with thinly sliced green onions and sesame seeds before serving immediately.
