Cook macaroni in boiling salted water until macaroni is tender. Rinse and drain. Cut chicken into 1"x1/2" pieces, put onto cookie sheet and drizzle with olive oil and broil on high for short time until browned. Combine macaroni and chicken with remaining ingredients, reserving enough cheese to sprinkle on top along with a little bacon and parsley. Put in a greased casserole dish and bake for about 1 hour at 375?.
