Pork Tenderloin Drenched with an Onion Sauce

The ingredient list and instructions for this recipe may look a bit intense, but that's because this is a full meal combined into one recipe. You could also grill the pork as the original intends, but I'm going to include the instructions for roasting instead. You might consider searing it prior to roasting.
