In a small bowl, combine the salt, pepper, garlic powder, onion powder, mustard powder and paprika. Mix the spices so they are well combined. Season the pork on all sides. You will have some leftover to use another time.
Prepare the pork tenderloins by trimming any fat and removing any silver skin. Drizzle the tenderloins with olive oil and season with spice mixture.
After the grill has preheated, cook the pork tenderloin until it reaches an internal temperature of 145F.
Remove the pork tenderloins to a plate, cover it with foil, and let it rest for 5-10 minutes before slicing.
Make the Creamy Mustard Sauce
Set a medium sauce pan over medium-high heat.
Add the butter, white wine, dijon mustard, and onion powder. Stir until it is well combined.
Bring the mixture up to a boil and let it cook for 2-3 minutes.
Add the chicken stock and honey. Bring the sauce back up to a simmer. Reduce the heat and cook the sauce for an additional 10 minutes.
To finish the sauce, add the heavy cream and check the sauce for seasoning. If needed, add salt or pepper. Bring the sauce up to a bubble and cook on medium-low for 5 minutes.
Turn off the heat and add fresh minced parsley if desired.
Serving Instruction
After the tenderloins have rested, slice them into ½" slices. Transfer the pork to a serving plate. Pour the creamy mustard sauce over the pork tenderloin or serve sauce on the side. Enjoy!

Notes
-The creamy mustard sauce will thicken as it cools.-The spice mixture for the pork is great on vegetables as well. I use the blend on roasted carrots and potatoes.
