Notes

If your natto doesn’t come with sauce, you can use soy sauce or make your own by mixing soy sauce, dashi, and sugar.
If you want crispy toast on all sides, toast it before adding toppings.
For a smoother texture, mix natto well.
If the natto smell is too strong, try adding curry powder or baking it with cheese.
