1 (14.5 oz) can fire roasted diced tomatoes (or regular diced tomatoes)
2 cups cooked chicken, shredded
2 cups frozen cheese tortellini
Fresh grated Parmesan cheese for serving
Instructions
Heat a 5-quart stock pot or Dutch oven over medium-low heat and add olive oil. Heat until shimmering, about 1 minute.
Add celery, carrots, and onion. Season with salt and pepper. Cook 5-6 minutes, stirring occasionally, until lightly softened.
Stir in garlic, Italian seasoning, and red pepper flakes. Cook 1 minute, stirring constantly, until fragrant.
Pour in chicken stock, red wine vinegar, and fire roasted tomatoes with juices. Bring to a boil, then reduce heat to low. Cover and simmer for 30 minutes.
Add shredded chicken and frozen cheese tortellini. Simmer uncovered for 5 minutes until tortellini is tender and floats to the top.
Taste and adjust seasoning. Serve hot with plenty of freshly grated Parmesan cheese.
Notes
Use any cooked chicken: breast, thighs, rotisserie, or leftover turkey. If using raw chicken, cook 1 pound of chicken breast or thighs completely before shredding and adding to soup.
