Begin by cutting the pressed tofu into 1-inch cubes.
In a medium bowl, coat the tofu cubes evenly with cornstarch, ensuring each piece is well covered.
Heat the vegetable oil in a large non-stick skillet over medium-high heat. Once hot, add the tofu cubes in a single layer (you may need to fry in batches) and cook until golden brown, about 3-4 minutes on each side. Remove tofu from the skillet and set aside on a plate lined with paper towels.
In the same skillet, reduce the heat to medium and add the minced garlic and grated ginger. Sauté for about 1 minute until fragrant, making sure not to burn the garlic.
Stir in the sweet chili sauce, soy sauce, and rice vinegar, mixing well. Allow the sauce to simmer for 2-3 minutes to thicken slightly.
Return the crisp tofu to the skillet and gently toss to coat the tofu cubes with the sauce. Cook for an additional 2-3 minutes, ensuring the tofu absorbs the flavors.
Once heated through, remove from heat and sprinkle chopped green onions over the top.
Serve immediately, garnished with sesame seeds and fresh cilantro, if desired.
Notes
Serve hot for the best flavor. Garnish with fresh cilantro for added freshness.
