Start a pot of water boiling... and while it is doing its thing, add some salt.
Then hopefully you have some:
* carrots
* mushrooms
* onions
* shallots or green onions
* parsley flakes
* black pepper
and a chopper/grinder you can put it all into.
Once the water is boiling you dump all the bits and pieces into the pot, and let the pot simmer for at least an hour. Taste and see what else is needed. I added some ginger, some cinnamon, and several tablespoons of potsticker sauce (somewhat spicey).
Serve with Brie or cheddar cheese and crackers of your choosing... or whatever else you might like to have with it.
Then you can watch the rain come down and still feel cheerful, I hope.
