Cut the tofu and enoki mushrooms into bite-sized pieces.
Heat cooking oil in a pan and grill the tofu on both sides until golden brown.
Place the enoki mushrooms on top of the tofu.
Mix soy sauce, water, oligosaccharide syrup, minced garlic, sesame oil, and pepper to make the sauce.
Pour the sauce into the pan and simmer over medium-low heat.
When it is nicely reduced, transfer to a plate and serve.
