Slice the pork to 1/2-inch thick & 3-4 inch wide for outdoor grill. For indoor stovetop, slice the pork to 1/4-inch thick.
Blend the ingredients under "Pork Marinade" (garlic, shallots, lemongrass, coconut aminos, fish sauce, olive oil, and black pepper) in a small 4-cup work bowl until a fine texture. Pour the marinade over sliced pork and let it sit overnight (or up to 24 hrs.) in the fridge.
Day of grilling:
Preheat a grill over medium-high heat. Slightly drip off the marinade and grill about 3-4 minutes per side or until the pork is cooked through and slightly charred on the surface. For 1/4-inch thick slices, grill about 6-8 minutes per side.
Serve with fresh lime wedges and enjoy while they are sizzling hot !
If not on whole30, try brushing the pork slices with 3 tsp raw honey mixed with 1 tsp water while grilling the pork to add extra sweetness flavor to the grill. If cook indoor over a stovetop, pan sear the pork slices in separate batches. Try not to over crowd the skillet
