The first thing you'll need to do is cook the pasta. Cook your chosen pasta according to the package directions in lightly salted water to al dente . When it is done drain the cooked pasta in a colander and rinse for several minutes with cold water. This helps cool the pasta quickly and stops it from cooking and softening any more.

While the pasta is cooking chop the chicken into bite size pieces and place in a large mixing or serving bowl. I like to season the chicken with buffalo sauce so I pour about at tablespoon full of buffalo wing sauce over the chicken and stir to coat.

Now in a small bowl mix together mayonnaise, sour cream, onion powder, and garlic powder. Add in buffalo wing sauce, if you like a more mild buffalo taste use ¼ of a cup, if you like it hotter add more, up to ½ of a cup. You can start with a smaller amount and add more to taste. Stir well.

Add the pasta to the bowl with the chicken, pour over the mayo mixture and stir to coat thoroughly. Add in blue cheese, green onions and celery and fold until evenly mixed. If you'd like you can reserve some green onions, celery, and blue cheese to garnish each serving as you plate it.
