Leaves from 1 thyme sprig
2 tablespoons unsalted butter
12 thin slices of prosciutto

Step 2: Apply cooking spray in a heavy skillet.
Step 3: Place the skillet on the stove and turn the heat to high.
Step 4: Add the tenderloin and sear all sides for 2 minutes, then remove it from the skillet to a clean plate.
Step 5: Remove the twine and brush mustard on all sides, then place it inside the fridge.
Step 6: Add the shallots, mushrooms, and thyme to the food processor. Pulse until well chopped.
Step 7: In the same skillet, add the butter and allow it to melt.
Step 8: Add the mixed mushroom mixture and cook for 25 minutes or until the water evaporates completely. Sprinkle salt and pepper to taste, then place it inside the fridge.
