Grilled Teriyaki Pork Loin - cooking recipe

Ingredients

3 lbs approx. boneless pork loin, trim fat
12 ounces teriyaki marinade (I use lawry's)

I first butterfly roast, leaving 1\" so it stays connected and flat. I then brine pork for about 3 hours (see brine recipes - I used everyday brine using water, sugar and kosher salt).
Remove from brine and place in ziploc with the teriyaki. place in fridge 24-48 hours.
get charcoals ashy on grill and place pork on it covered for 18 minutes. Flip and cook approximately 10 more minutes.
Remove onto plate and rest 5-10 minutes. I cut into 1-2\" thick slices.
