Wash and chop the broccoli into bite-sized florets. Slice the red bell pepper and set aside. Rinse the snap peas and set aside as well.
In a small bowl, whisk together the honey, soy sauce, sesame oil, minced garlic, grated ginger, and cornstarch (if using). Add water to thin out the mixture slightly. Set aside.
Heat a large skillet or wok over medium-high heat. Add a drizzle of oil (optional) to prevent sticking and make it non-stick.
Add the broccoli florets to the hot skillet and stir-fry for about 3 minutes. Then add the sliced bell pepper and snap peas, continuing to stir-fry for another 2-3 minutes until the vegetables are bright and tender-crisp.
Pour the honey garlic sauce over the vegetables and stir to coat everything evenly. Cook for an additional 1-2 minutes, letting the sauce thicken and glaze the vegetables.
Taste and adjust seasoning with salt and pepper as needed.
Serve the stir-fried vegetables over a bed of cooked rice or quinoa, garnishing with sesame seeds for an added touch.
