Boil the chicken in water for 15 minutes until cooked. Shred the chicken with two forks and mix with blue cheese dressing. Set aside.
In a large skillet, melt butter over medium heat. Add onions and celery, cooking for 5 minutes until soft. Then, add garlic and cook for 1 more minute.
Add undrained tomatoes and chicken broth to the skillet. Bring to a boil, then add pasta. Cook for 10-13 minutes until al dente.
Reduce heat and add buffalo sauce, cream cheese, and shredded cheese. Gently stir until the sauce thickens.
Mix in the shredded chicken and red pepper flakes.
Optional: For a smooth finish, swirl in 2 tbsp of cold butter once the sauce is almost at your desired consistency.
