Step 1

In a Dutch oven, heat oil over medium-high heat. Add mushrooms; cook and stir until tender, 6-8 minutes. Add garlic; cook 1 minute longer.

Step 2

Add broth and tomatoes; bring to a boil. Add tortellini; cook, uncovered, just until tortellini float (do not boil), 3-4 minutes. Stir in spinach and pepper; cook just until spinach is wilted. If desired, serve with cheese.
