Cut 1/2 block of tofu into rectangular pieces and pat dry with a paper towel.

Heat a pan with 2 tbsp cooking oil and fry tofu until golden on both sides. Set aside.

Add a little cooking oil to the pan and sauté chopped vegetables (onion, carrot, green chili) until softened.

Add 2 tbsp ketchup, 2 tbsp tonkatsu sauce, 0.5 tbsp minced garlic, and 1 tbsp oligosaccharide to the pan. Stir well.

Pour in 1/3 cup water and mix thoroughly. Cook until the sauce thickens slightly.

Add the fried tofu to the pan and braise until the sauce is absorbed. Sprinkle ground pepper to taste.
