Pat the chicken breast dry with paper towels and dice into 1-inch pieces.
In a medium bowl, toss the chicken with cornstarch, sea salt, and black pepper until evenly coated.
In a small jar or bowl, whisk together the honey, tamari, minced garlic, and grated ginger to create the sauce.
Heat the extra virgin olive oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and sear for 5-6 minutes, turning occasionally until golden brown and cooked through.
Remove the chicken from the pan and set aside; add the broccoli, bell pepper, and snap peas to the same skillet with 2 tablespoons of water.
Cover and steam the vegetables for 3 minutes until they are vibrant and crisp-tender.
Return the chicken to the skillet, pour the honey-garlic sauce over the top, and stir constantly for 1-2 minutes until the sauce thickens into a glossy glaze.
Garnish with sesame seeds and serve immediately.
