Cut the tofu into bite-sized pieces and pat dry with a paper towel.
Add cooking oil to a pan and fry the tofu on both sides until golden brown.
Mix soy sauce, water, minced garlic, oligosaccharide syrup, and sesame oil to make the sauce.
Pour the sauce over the fried tofu and simmer on low heat until reduced.
Finish by sprinkling sliced green onions and sesame seeds on top.
