Follow these clear steps to create your Vegetable Tofu Stir Fry:

1. Prepare the Tofu: Press the tofu to remove excess moisture. Cut it into bite-sized cubes.

2. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat.

3. Cook the Tofu: Add the tofu cubes to the pan. Cook them until they are golden brown and crispy on all sides, about 6-8 minutes. Remove the tofu from the pan and set aside.

4. Stir-Fry Vegetables: In the same pan, add more oil if needed. Add the garlic and ginger, stirring quickly to prevent burning.

5. Add Vegetables: Toss in the bell peppers, broccoli, carrots, and snap peas. Stir-fry for about 5-7 minutes until the vegetables are vibrant and tender-crisp.

6. Combine Tofu and Sauce: Return the cooked tofu to the pan. In a small bowl, mix the soy sauce, sesame oil, and cornstarch (if using). Pour the sauce over the tofu and vegetables, stirring well to coat.

7. Cook and Thicken: Allow everything to cook together for another 2-3 minutes, letting the sauce thicken and cover the ingredients evenly.

8. Season: Taste and adjust seasoning with salt and pepper as desired.

9. Serve: Remove from heat and serve immediately over cooked rice or noodles. Garnish with sesame seeds if desired.

This straightforward process ensures that your Vegetable Tofu Stir Fry is both delicious and easy to make!
