For the Pork Tenderloin:
In a gallon sized zipper bag, mix together the maple syrup, apple cider, garlic, mustard, olive oil, and salt. Add the pork tenderloins and turn to coat completely.
Marinade in the fridge 4-24 hours.
Heat the oven to 400F.
Place the pork on a foil-lined baking sheet and roast until the internal temperature is 140F degrees, about 25-30 minutes. You can also grill the pork tenderloins for about 15 minutes.
Let rest 5-10 minutes, then slice and serve with Caramelized Apples.
For the Caramelized Apples:
Peel and core the apples. Slice into 1/2 inch wedges.
In a large saute pan over medium-low heat, melt the butter and sugar until the sugar is dissolved.
Add the apples and stir to combine well. Cook until the apples are soft, about 10 minutes.
Add the cinnamon, lemon zest, and apple cider. Stir to combine well. Continue to cook until the liquid has thickened slightly, about 2 minutes.
Serve with Maple Pork Tenderloin.
