Cocoa Coffee Rubbed Pork Tenderloin Medallians

for this you will need:

2 Pork tenderloins
Wet:
4 Tablespoon hot mustard
2 Tablespoon ballpark mustard
2 cloves crushed garlic
1/4 cup diced white onion
2 chipotle peppers in adobe, seeded
1 Tablespoon Olive oil
Dry:
6 Tablespoon fine ground french roast coffee
2 Tablespoon raw unsweetened cocoa
2 Tablespoon Spanish paprika
1 Tablespoon wasabi powder
1 Tablespoon  onion powder
2 Tablespoon Kosher Salt or Red clay salt if you can find it.. finely ground

Make sure you get all the silver-skin and unwanted fat trimmed off your pork tenderloins.

Combine in a blender / magic bullet your mustards, onion,crushed garlic and chipotle and oil, what we are creating here is a a little "glue" to give the rub something to stick to, and to add another level of flavor.
Dry off your pork tenderloins with a paper towel and then get in there with your "glue" and cover every surface of the pork, you may want to fold over and tie up the thin end of your tenderloins to ensure even cooking. 
Next  combine all your dry ingredients, and spread out onto a plate that you will be able to roll your tenderloins in. roll the tenderloins in the rub, then tightly wrap the tenderloins in plastic wrap and refrigerate overnight.

Cook your loins on direct medium high heat (350-450) until the internal temperature reaches at least 145f. Rest the loins under a tent of foil for at least 10 minutes so your liquid stays in the meat and not on the plate, carefully slice into 1 inch medallions ensuring that  every slice has lots of the delicious crust on it. Feel free to top with chives and  your favorite mustard or bbq sauce.
