"Super-easy vegan miso soup packed with vitamins and flavor! Makes a great appetizer to fill you up or an accompaniment to any entree! Feel free to try sauteeing chopped carrots, watercress, beans, or others in addition to the vegetables in the ingredients list."
Heat olive oil in a saucepan over medium heat. Add onion, celery, and spinach. Cook and stir until just softened, about 3 minutes. Pour in water; add tofu and salt. Reduce heat to medium-low; simmer until heated through, about 8 minutes.
Stir in miso; simmer until dissolved, about 5 minutes. Season with ground black pepper and chili powder.
