Place 2 tablespoons vegetable oil, 1 teaspoon ginger, garlic, and cornstarch in a large bowl; mix until cornstarch is dissolved.
Add broccoli, carrots, snow peas, and green beans; toss lightly to coat.
Heat remaining 2 tablespoons vegetable oil in a large skillet or wok over medium heat. Add vegetable mixture and cook for 2 minutes, stirring constantly to prevent burning.
Stir in water and soy sauce; add onion, salt, and remaining 1 teaspoon ginger. Cook and stir until vegetables are tender but crisp.
