Preheat oven to 400 degrees. Place a rack inside a rimmed baking sheet and set aside. If you don’t have a rack, line your baking sheet with foil and lightly coat it with oil or cooking spray.
In a large bowl, whisk together vinegar, honey, vinegar oil, mustard, salt and pepper. Continue whisking as you stream in oil. Whisk until mixture is well combined. Remove 1/2 cup of dressing and reserve as a dipping sauce for later. Add chicken tenders to the remaining dressing and toss to coat.
NOTE: You can prepare the chicken up to this point a few hours ahead of time and allow it to sit in the marinade in the refrigerator, covered in plastic wrap.
Remove pieces of chicken from marinade allowing any excess dressing to drip off. Place chicken into crushed pretzels and press down firmly so coating sticks. Lay chicken on prepared baking sheet. Bake chicken for 20-25 minutes (depending on the thickness of your chicken). Do not over cook or it will dry out.
