Start by preparing the tofu. After pressing it to remove excess moisture, cut the tofu into 1-inch cubes and toss them in cornstarch until evenly coated. This will give the tofu a crispy texture when cooked.
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Once hot, add the tofu cubes in a single layer and cook until golden brown and crispy on all sides (about 2-3 minutes per side). Remove the tofu from the skillet and set it aside.
In the same skillet, add the remaining tablespoon of oil. Add in the sliced red bell pepper, snap peas, and julienned carrot. Stir-fry the vegetables for about 3-4 minutes until they are tender but still crisp.
Add the minced garlic and grated ginger to the skillet and cook for another minute until fragrant.
Return the crispy tofu to the skillet with the vegetables. Pour in the Sriracha sauce, soy sauce, and honey or maple syrup. Toss everything together to coat the tofu and veggies evenly with the spicy sauce. Cook for an additional 1-2 minutes, allowing the flavors to meld.
Season with salt and black pepper to taste. Once done, remove the skillet from heat.
Serve the stir-fry hot, sprinkled with sesame seeds and topped with fresh cilantro.
Notes
Pressing the tofu is essential for achieving a crispy texture.
