I can't claim the credit for this one; it came from a fantastic book called Hoax Cooking.
1 pre-cooked whole chicken from the supermarket
1 jar kalamata olives
1/2 jar sun-dried tomatoes
1 jar basil pesto
penne pasta, cooked (duh right)
Basically, take apart the chicken - get rid of the skin and bones. Mix together chicken and all other ingredients. Serve! Very easy and impressive:)
