Spicy Garlic Lime Chicken Pasta

What a great summertime dinner! This is the second time I have made this dish and we really enjoy it. The subtle lime taste is nice and refreshing and I love the spicy heat in the back ground of the dish. I made exactly like the recip the first time and this time I tweaked it just a bit. Changes are noted in bold.

Spicy Garlic Lime Chicken Pasta
(Recipe Courtesy of Amber)

Ingredients:
1 cup chicken broth
1.5 tbls lime juice (adjusting amount to your liking)
1 tbls corn starch (I used more like a tbsp and a half)
3 cloves garlic, minced
1/2 tsp salt
1/4 tsp black pepper
1/8 tsp cayenne pepper (I used a lot more than this, I like things spicy!)
1/4 tsp paprika
1/4 tsp garlic powder
1/4 tsp onion powder (I used dried onion flakes instead)
1/4 tsp dried thyme (I ommitted this)
1/4 tsp dried parsley (I ommitted this)
2 boneless skinless chicken breasts (cut into bite size pieces)
1 tbls butter
Few drizzles of olive oil
8 oz pasta (I used whole campanelli)
1-2 cups broccoli florets
Optional - Parmesan cheese for topping

Directions:
1) Bring pot of salted water to a boil. Cook pasta according to package directions. During the last 5 minutes of pasta cook time add the broccoli into the boiling water. Drain.
2) Mix together all the sauce ingredients (chicken broth through parsley) and set aside. (I actually cut the chicken into pieces and then put the spices right on the chicken like a dry rub)
3) Meanwhile, heat butter and olive oil in saucepan over medium heat. Add bite size chicken pieces into heated pan. Cook chicken until no longer pink. Pour the sauce ingredients into the pan with the chicken and bring to a simmer. Let simmer until chicken is cooked through and sauce has thickened. (When the chicken was finished I added the cornstarch then when that was dissolved I added the lime juice and then the chicken broth)
4) Toss cooked broccoli and pasta with the chicken and sauce (I let it simmer for another 2 minutes in the sauce!). Sprinkle with parmesan cheese if desired and serve.
