Tuscan Tortellini Soup

In a large pot over medium heat, heat oil. Add onion and cook, stirring occasionally, until softened, about 7 minutes. Add sausage and cook, stirring occasionally, until browned, about 4 minutes. Add garlic and cook, stirring, until fragrant, about 1 minute more.

Stir in broth, tomatoes and red pepper flakes; generously season with salt and black pepper.

Bring to a boil and add tortellini. Reduce heat to medium-low and simmer, stirring occasionally, until tortellini is cooked through, about 5 minutes.

Stir in beans and spinach and cook, stirring, until spinach is wilted, about 2 minutes more. Top with Parmesan.
