Bring a large pot of lightly salted water to a boil. Add pasta and cook for 5 to 8 minutes or until al dente. Drain.
Heat olive oil in a large skillet over medium heat. Add chicken pieces, and cook, stirring until browned on the outside. Stir in the garlic, basil, Cajun seasoning, salt, and pepper, then mix in the tomatoes. Cook until tomatoes are semi soft, and chicken is cooked through. Toss with pasta, and serve with crumbled feta cheese on top.
