In a small bowl, whisk together the gochujang paste, coconut aminos, toasted sesame oil, and raw honey until smooth.
Heat the avocado oil in a large wok or skillet over medium-high heat until shimmering.
Season the cubed chicken breast with sea salt and black pepper, then add to the pan and sear until golden brown and fully cooked.
Add the sliced red onion, bell pepper, and sugar snap peas to the skillet, stir-frying for 3-4 minutes until the vegetables are tender yet crisp.
Stir in the minced garlic and fresh ginger, cooking for 30 seconds until the aromatics are fragrant.
Pour the prepared gochujang sauce over the chicken and vegetables, tossing constantly for 1 minute until the sauce thickens into a glossy glaze.
Serve the stir-fry immediately over the cooked brown rice and garnish with sesame seeds.
