Tonight's quick miso soup

Filled & started electric tea kettle.
In the meantime diced up some onions and carrot, about :

• diced quarter of a large red onion
• diced small carrot

Saute'ed in a few tablespoons oil.
Added a chunk of miso. About

• 3 tablespoons? miso

Stirred in the hot water, with about 2 tablespoons of leftover tomato-basil sauce to use it up from the jar.
Added about

• 3/4 cup frozen spinach

Sprinkled in the following spices:

• ginger (very little)
• sage (tiny bit)
• cumin
• coriander 
• garlic powder
• a bit of black pepper

It's not great, but not as terrible as experimentation might warrant. Rather warm and soothing.
Just recording the ingredients for improvement later.
I think the ginger is important, even though in a small quantity.
