Just a pinch of saffron goes a long way in adding flavor and intense color to food. The aromatic spice is a tad expensive, so feel free to leave it out. This quick dinner soup is terrific with or without it.
Lightly coat an unheated large saucepan with nonstick cooking spray. Preheat over medium-high heat. Add chicken; cook and stir for 3 minutes. Carefully add broth, leek or onion, ginger, and, if desired, saffron.
Bring to boiling. Add tortellini or ravioli. Return to boiling; reduce heat. Simmer, uncovered, for 5 to 9 minutes or until tortellini or ravioli is tender, stirring occasionally. Remove from heat. Top individual servings with spinach. Makes 4 servings.
