What To Do:
1. Make Dressing: In a small bowl, whisk together vinegar, mustard, honey, shallot, 1½ tablespoons olive oil, and salt and pepper to taste. Toss in fennel and let stand.
2. Cook Chicken: Coat a grill pan with olive oil and place over high heat. Salt and pepper the chicken tenders and place on the hot grill. Cook until juices run clear, turning once (about 15 minutes). Remove to a plate and allow to rest for 5 minutes.
