You don't need to add sugar or salt. The oatmeal tastes sweet. I eat them with 2 slices of bacon that give me some salty flavor.
Kabocha is a pumpkin-shaped Japanese squash with honeyed sweetness. It has jade green exterior and light green stripes. The meat of kabocha squash is a pale orange. I cut it in half after washing it thoroughly. I baked half of it for other use (adding to salad etc. ) and cut the other half in chunks for my oatmeal breakfast.
