Preheat oven to 400F. Line a baking sheet with foil. Toss wings in oil and place on the baking sheet. Sprinkle with salt and pepper. Bake for 30-35 minutes, flipping half way through.
In the meantime, make sauce. In a small bowl, whisk together stone ground mustard, honey, garic, apple cider vinegar, and a pinch of salt. Set aside until wings are ready.
Once wings have finished cooking through in the oven, turn the oven to broil. Broil the wings for 5-7 minutes, watching carefully, until they are crispy.
Remove from the oven, add wings to a large bowl and pour honey mustard sauce over the wings. Toss until wings are completed covered.
