In a small bowl, whisk together coconut aminos, rice vinegar, honey, and arrowroot powder until the starch is fully dissolved.
Cut the chicken breast into bite-sized cubes and season with sea salt and black pepper.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the minced garlic, grated fresh ginger, sliced bell peppers, and sugar snap peas, sautéing for 3 minutes until vibrant and crisp-tender.
Add the pineapple chunks and return the cooked chicken to the skillet.
Give the sauce mixture a quick whisk and pour it over the chicken and vegetables.
Toss everything constantly for 1 to 2 minutes until the sauce thickens into a glossy glaze that coats every piece.
Serve the stir-fry immediately over the warm cooked jasmine rice.
