This easy soup was on our menu the week of 3/23/15 and took advantage of the convenience of storebought tortellini. Served in a creamy soup, it's a great cold weather meal. This time around, we recommend using plain yogurt instead of cream to add thickness to the soup since you'll already be using yogurt earlier this week.
Cook tortellini according to package instructions and then drain.
Heat a Dutch oven over medium-high heat. Add cooking oil and then garlic, onions, and carrots to heated oil with a sprinkle of salt, red pepper flakes, and basil. Saute for ~5 minutes.
Add tomatoes, broth, and some salt and pepper. Bring to a boil and then simmer for 4 to 6 minutes.
Puree with an immersion blender or in batches in a blender. If using an immersion blender, you might want to transfer pot into sink since there might be spattering.
Return pot to medium-high heat and fold in mushrooms. Cook until tender, 3 to 4 minutes.
Turn off heat, and stir in yogurt (if using), tortellini, and spinach. Finish with lemon juice, and season to taste with more salt and pepper. Enjoy your comforting soup!
