Get your grass skirt and coconut bra out of the closet (what, you don't have those hanging next to your winter coat?) and say aloha to this low-cal, low-carb powerhouse. Pork medallions marinate in a sweet combination of teriyaki, sesame, and, of course, pineapple and are cooked with the added heat of that hip hot sauce, Sriracha. Paired with a crisp sesame slaw, you'll forget you're on the snowy mainland as soon as you take one bite.
Trim and cut 2" pieces from green tops of green onions. Slice pieces into very thin strips and place in a small bowl of cold water to "curl" into a garnish (optional). Trim and thinly slice remaining green onions on an angle, keeping white and green portions separate. Rinse pork tenderloin and pat dry. On a separate cutting board, slice tenderloin into 8-10 medallions, ½"-¾" thick. Season both sides with ¼ tsp. salt and ¼ tsp. pepper.
Marinate the Pork
In a large mixing bowl, combine teriyaki glaze, white portions of green onions, half the sesame oil (reserve remaining for slaw dressing), half the rice vinegar (reserve remaining for slaw dressing), and half the pineapple juice (reserve remaining for glaze). Place pork medallions in marinade, toss to coat evenly, and let sit 10 minutes. While pork marinates, make dressing.
Make the Dressing
In another large mixing bowl, combine mayonnaise, remaining rice vinegar, remaining sesame oil, green portions of green onions (reserve "curling" green portions for garnish), and a pinch of salt and pepper.
Add Slaw and Finish Marinating Pork
Add slaw mix to mixing bowl with dressing and toss to coat. Season with a pinch of salt and pepper and set aside. Remove pork from marinade and pat very dry with paper towels. Reserve marinade.
Cook the Pork
Heat 2 tsp. olive oil in a large non-stick pan over medium-high heat. Add pork to hot pan and cook until pork reaches a minimum internal temperature of 145 degrees, 3-4 minutes per side. Remove pork to a plate. Add marinade, remaining pineapple juice, and half the Sriracha to pan and cook, stirring occasionally, until a sticky glaze forms, 3-4 minutes. Taste, and add remaining Sriracha if desired. Remove from burner, return pork and any accumulated juices to pan, and flip to coat.
Plate the Dish
Place a serving of slaw in middle of a plate. Serve pork medallions and sauce against slaw. Garnish with curled green portions of green onions.
