Jeff's Chicken Tortellini Soup

Combine chicken broth, butter, garlic, thyme, and red pepper in a 6-quart soup pot. Bring to a boil. Add tortellini; cook until they float to the top, 3 to 5 minutes.

Stir cooked chicken, spinach, cream of chicken soup, half-and-half, and green onions into the pot with the tortellini. Reduce heat and let simmer until heated through, about 10 minutes more.
