Pound the chicken breast until quite thin (around ¼”³ thick). Mix all of the spice ingredients together thoroughly. Coat both sides of the chicken breasts with the spices.
Heat a non-stick grill pan or skillet over medium high heat. Place chicken breasts in pan and brown both sides, 45-60 seconds per side. Place chicken in prepared baking pan and bake in oven for 5 minutes. Remove from oven and slice chicken into strips.
Cook pasta according to package directions. Drain and return pasta to warm pot over medium-low heat. Pour in alfredo sauce and mix thoroughly.
Serve pasta with sliced chicken served on top. Serves 4.
