　　The distinct flavors of fresh cilantro and curry powder, along with the unexpected addition of peanut butter, turn a simple tomato-based soup into something special. You can make it vegetarian by using vegetable broth.

Ingredients

　　1 medium onion, chopped (1 cup)

　　1/4 teaspoon salt

　　1/8 teaspoon black pepper

　　2 tablespoons vegetable oil

　　2 teaspoons curry powder (preferably Madras)

　　1 (14-oz) can diced tomatoes in juice, chopped if large, reserving juice

　　1 3/4 cups reduced-sodium chicken broth (14 fl oz)

　　1 cup hot water

　　1/4 cup smooth peanut butter

　　2 tablespoons chopped fresh cilantro

　　Cook onion, salt, and pepper in oil in a 2- to 3-quart heavy saucepan over moderate heat, stirring occasionally, until softened, 4 to 5 minutes. Add curry powder and cook, stirring frequently, 2 minutes. Add tomatoes (with their juice) and broth and simmer, uncovered, 5 minutes. Stir hot water into peanut butter until smooth and add to soup. Simmer, uncovered, stirring occasionally, 5 minutes. Stir in cilantro before serving.
