Prepare all vegetables by washing and cutting them into bite-sized pieces.
Heat sesame oil in a large pan or wok over medium-high heat.
Add minced garlic and grated ginger; sauté for 30 seconds until fragrant.
Add broccoli florets and bell peppers; stir-fry for 3-4 minutes.
Incorporate snap peas and continue to stir-fry for another 2-3 minutes.
Pour soy sauce over the vegetables, stirring to coat evenly.
Season with salt and pepper to taste.
Cook for an additional 1-2 minutes until vegetables are tender yet crisp.
Remove from heat and sprinkle with sesame seeds if desired.
Serve hot over cooked rice or noodles.
