Begin by pressing the tofu to remove excess moisture. Once pressed, cut the tofu into 1-inch cubes.
In a mixing bowl, toss the cubed tofu with cornstarch until evenly coated. This will help create a crispy texture when cooked.
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the tofu cubes and cook until golden brown and crispy on all sides, approximately 8-10 minutes. Remove the tofu and set aside.
In the same skillet, add the remaining tablespoon of oil. Add the sliced bell peppers, broccoli florets, and snap peas; stir-fry for about 5 minutes or until the vegetables are tender-crisp.
Add the minced garlic and grated ginger to the vegetables, cooking for an additional minute until fragrant.
Return the crispy tofu to the skillet. Pour in the sweet chili sauce, soy sauce, and rice vinegar. Stir to combine and cook for another 2-3 minutes, allowing the sauce to coat the tofu and vegetables.
Season with salt and pepper to taste, adjusting as necessary.
Remove from heat and garnish with sliced green onions and sesame seeds.
Notes
Serve the stir fry in individual bowls, with a sprinkle of sesame seeds and a few slices of green onion on top for a fresh touch. Pair it with steamed jasmine rice for a complete meal.
