Fennel seeds give this tomato and balsamic sauce an extra kick, but if you don't have them on hand, try using cumin or coriander seeds. Serve this easy chicken breast recipe with whole-wheat spaghetti or crusty bread to sop up the sauce. Save the unused chicken tenders in an airtight container in your freezer for up to 3 months. Once you have enough, thaw them out for another use.
