Cut soft tofu into bite-sized pieces.
Slice green onions and spicy chili peppers.
Heat cooking oil in a pan and stir-fry the green onions for flavor.
Place the tofu in the pan, then add soy sauce, water, sugar, and minced garlic.
Add spicy chili peppers and simmer over medium-low heat.
Once the sauce thickens slightly, it's ready to serve.
