In a large pot, bring water to a boil and cook pasta according to the package instructions and drain well when done.
In the meantime, brown your chicken in a large skillet on medium-high heat, 3 minutes on each side.
While the chicken is browning, combine hot sauce, ranch dressing, and onion powder in a small bowl and set aside.
Once chicken is done browning, remove and set aside on a plate. In the same skillet, throw in the celery and carrot and cook until tender. Then place the chicken back in the skillet along with the sauce mixture.
Let sauce simmer for 3-4 minutes then add the pasta to the sauce. Stir until well coated and all is combined.
