This soup is perfect for these days (weeks!) spent in the single digits. Mmm..
Bring to a boil 1 cup veggie broth. Add cubed tofu and sliced scallions. Add strips of nori or other seaweed til softened. Remove from heat.
Stir in 2 tsp miso paste (any kind will do - the lighter the miso the lighter the flavor).
I didn't have any tofu or scallions, so mine is loaded with nori. Turns out my dog loves nori! Nori doesn't hold up as firmly as the other seaweeds like wacame, but if you have it around, it'll do fine.
