Sumo wrestlers eat lots of "nabe" to get up to fighting weight. We've toned our salmon soup down a lot, so this really isn't going to pack on the pounds unless you eat it with a LOT of rice. Sumo wrestlers have their own recipes and vary the soup depending on the ingredients they have. This is our version of Ishikari Nabe, using ingredients that we are readily able to find here. It isn't authentic, but works with our kids. The recipe is meant to be adjusted to incorporate things you may have at hand. We often add spinach, squash, green onions, sweet onions, mushrooms. You can add the eggs if you want, usually the tofu and salmon are plenty for us. If you really want to eat like a sumo wrestler, you should just dump your STEAMED rice right into the soup.
