In a bowl, whisk together the marinade ingredients until smooth. For the pork, place all of the pork and half of the marinade ingredients into a ziploc bag. Let them marinate for 1 to 8 hours, or until ready to grill. Once you are ready to cook, heat an outdoor or indoor grill to high heat. Place the pork pieces onto the grill and grill on one side until golden brown and nice and charred. Turn the pork pieces over and continue to cook until the center of the pork is no longer pink. Once the pork is done cooking, remove from the heat and place in a bowl. Add the remainder of the marinade to the pork and toss to coat. Let the pork sit aside and rest while you prep the tacos.
For the Sriracha sauce, add the ingredients together until smooth.
For the taco ingredients, prep the vegtables and slice. When ready to serve, slice the pork into thin strips. Serve the warm pork in the tortillas with the fresh vegetables and Sriracha sauce. Serve.
