Cut the tofu into bite-sized pieces.
Season the tofu with salt and pepper.
Lightly coat the tofu with corn starch.
Heat cooking oil in a pan and fry the tofu on both sides until golden brown.
In a separate bowl, mix gochujang (Korean chili paste), soy sauce, oligosaccharide syrup, minced garlic, and vinegar to make the sauce.
Add the sauce to the fried tofu and stir-fry over medium-low heat.
Turn off the heat and sprinkle with sesame seeds and chopped green onions.
