Ingredients

3 cups homemade or low-sodium canned vegetable or chicken stock, skimmed of fat 

2 cups water 

2 carrots, cut into matchsticks (about 1 cup) 

1/3 pound spinach, stems removed, cut into 1-inch strips 

6 ounces extra-firm tofu, cut into 3/4-inch cubes 

2 tablespoons white miso 

1 scallion, sliced crosswise into 1-inch strips 

Preparation

In a medium saucepan, bring stock and the water to a boil over high heat. Reduce heat to medium-low, and add carrots. Cook until carrots are crisp-tender, about 2 minutes.

Add spinach and tofu, and stir to combine. Continue cooking just until spinach is wilted and tofu is heated through, about 1 minute more.

Meanwhile, place miso in a small bowl, and stir in 1/4 cup cooking liquid until miso is dissolved. Add mixture to saucepan, stirring to combine. Do not let soup boil once miso has been added.

Remove from heat. Ladle soup into four serving bowls. Sprinkle each with scallions. Serve immediately.
