Juicy grilled steak slices paired with tropical fruits like pineapple, layered with crisp greens and a zesty sauce on a hearty roll for a sweet and savory bite.
Whisk together olive oil, vinegar, garlic, and ginger. Toss the steaks and pineapple in the marinade, and refrigerate for one hour.
Meanwhile, whisk together mayonnaise, yogurt, orange juice, coriander, and curry powder in a separate bowl.
Preheat a grill for medium-high heat. Remove the steaks and pineapple from the marinade, and discard marinade.
Grill the filets and pineapple for about 5 minutes per side, or to desired doneness. Spread the mayonnaise mixture onto 2 slices of sourdough bread. Top with steaks, lettuce and remaining slices of bread.
