Preheat oven to 400 degrees.
In a food processor, pulse together the pretzels and panko. If you don't have a food processor place pretzels and panko into a sealed ziploc bag and crush with rolling pin until you get a coarse consistency.
Place the flour, salt and pepper in one shallow dish. In another shallow dish whisk together the mustard, honey, olive oil, and white wine vinegar. In a final shallow dish place pretzel mixture.
Coat each chicken tender in flour first, then mustard mixture, then in pretzel mixture.
Place on a greased baking sheet. Bake for 14-16 minutes until cooked through.
