2 Tbsp. grainy Dijon mustard (or any mustard you like)
2 Tbsp. chopped fresh rosemary
1Cut the pork tenderloin in half widthwise, then into even strips lengthwise. Put them into a ziplock bag along with the marinade ingredients; knead the bag a bit to blend everything, then stash in the fridge for up to 24 hours or in the freezer for up to 6 months.
2When ready to grill, soak bamboo skewers for at least 10 minutes, then thread the pork onto the skewers and grill for a couple minutes per side (depending on the thickness of the pork), just until done. Serve hot, warm or cold, preferably with peanut sauce.
