Press your tofu for about 10 minutes between paper towels with a heavy object to remove moisture.

Cut the tofu into 1-inch cubes.

In a bowl, toss the cubed tofu with cornstarch and salt. Let it rest for at least 5 minutes.

Mix sweet chili sauce, soy sauce, rice vinegar, garlic, ginger, sesame oil, and red pepper flakes in a separate bowl.

Heat vegetable oil in a non-stick skillet over medium heat until shimmering.

Fry tofu cubes in a single layer for 3-4 minutes on each side until golden brown.

Reduce heat to low and pour the sauce over the fried tofu, gently tossing to coat.

Cook for an additional 1-2 minutes until the sauce thickens slightly.

Garnish with sliced green onions and sesame seeds. Serve immediately over cooked rice or quinoa.
