Heat the butter in a frying pan. Sauté the minced onion and green peppers.
When cooked, add 2/3 of the okara into the frying pan and stir-fry quickly.
Add water, soup stock granules and the ketchup. If it's too dry, add some soup stock dissolved in water. If it tastes too plain, add more ketchup.
Beat the eggs. Mix in the rest of the okara, salt and pepper.
Heat some oil in a frying pan and cook the egg.
Slide the omelet onto the ketchup rice to finish.
Story Behind this Recipe
I wanted to make low calorie omurice that you can depend on even when you're on a diet.
The ketchup rice becomes thick after adding the okara, making it hard to cook. Don't give up! This recipe doesn't use any meat since it's a dieter's recipe, but it's also good with some chicken. With okara, you can make the ketchup rice and omelette thick and fluffy.
