In a medium non-stick skillet over medium-high heat, add the sausage and use a spatula to break into bite-size "meatballs". Cook, stirring occasionally, until the sausage in browned. Reduce heat to low, then add the garlic and stir until fragrant, about 30 seconds.
Add the broth, tomatoes, cream, and tortellini to the skillet. Stir to combine. Increase heat and bring to a boil.
Cover, then reduce the heat and simmer for 15 minutes until tortellini are tender and heated through. Season to taste with salt and pepper, and then stir in the spinach. Remove from heat, spoon up into bowls, and serve!
