Gather all your ingredients and have a paper towel ready to pat the chicken dry. Slice the chicken breasts thinly and toss them in cornstarch, ensuring each piece is lightly coated.
Heat your wok or skillet over high heat until it shimmers, then add the oil, swirling to coat the surface evenly.
Once the oil is hot and just starting to smoke, carefully add the chicken slices in a single layer. Let them sear undisturbed for about 2 minutes until the edges turn golden and crispy.
Flip the chicken pieces and cook for another 1-2 minutes, until cooked through and crispy on all sides. Remove the chicken from the pan and set aside on a paper towel to drain excess oil.
Lower the heat slightly to medium-high and add the sliced bell pepper and snap peas to the pan. Stir-fry for 2-3 minutes until vegetables are bright, slightly charred, and still crisp.
Add the minced garlic and grated ginger, cooking for about 30 seconds until fragrant and just starting to turn golden, stirring constantly to avoid burning.
Return the crispy chicken to the pan, then pour in a mixture of soy sauce, honey, and sesame oil. Toss everything quickly to coat evenly and cook for another minute until the sauce is glossy and heated through.
Turn off the heat and drizzle a little more sesame oil if desired. Give everything a final toss, then transfer to plates. Serve immediately to enjoy the crispy texture and vibrant flavors.
