Prepare all vegetables by washing and chopping them accordingly.
Heat vegetable oil in a large wok or skillet over medium-high heat.
Add minced garlic and ginger, sautéing for about 30 seconds.
Incorporate the broccoli and carrots into the wok, stir-frying for 2–3 minutes.
Add the sliced bell pepper, snap peas, and mushrooms; continue to stir-fry for another 3–4 minutes.
Pour in soy sauce and sesame oil, stirring well to coat the vegetables.
Cook for an additional minute, then remove from heat.
Serve hot, garnished with sesame seeds.
