Cajun Coconut Chicken Pasta

1 1/2 lbs. of chicken breasts, cut into bite-size pieces, uncooked
2 Tbsp. olive oil
1 Tbsp. Cajun seasoning of your choice
2 Tbsp. butter
2 cups coconut milk
1 cup heavy whipping cream
1/4 tsp. garlic powder
1 Tbsp. corn starch
1 tsp. black pepper
1 package or box of rotini pasta
2 roma tomatoes, chopped
3/4 cup green onion, chopped
Shredded parmesan

Cook pasta according to directions.  In a skillet on medium high heat add olive oil to the pan and chicken.  Sprinkle the cajun seasoning over the chicken as it cooks.  Cook for about 5-7 minutes or until chicken is fully cooked.  While chicken is cooking, in a medium sauce pan combine butter, cream, coconut milk, garlic powder and pepper.  Remove about a cup of the sauce and whisk in the cornstarch and then pour it all into the sauce.  Heat until boiling, stirring frequently.  Once the sauce is done combine it with the drained pasta and chicken.  Serve and top with tomatoes, green onion and parmesan.
