Instructions

  1. In a small bowl, combine the cucumbers, sour cream, and dill. Refrigerate until needed.
  2. Cut the pork across the grain into 1/2-inch cutlets; then slice each piece into thin strips.
  3. In a large bowl, combine the mustard, oil, lemon juice, garlic, and oregano. Add the pork and toss well to coat all the pieces. Let stand about 10 minutes.
  4. Coat a large no-stick frying pan with no-stick spray, and place over medium heat for 3 minutes.
  5. Working in bunches to avoid overcrowding in the pan, add the pork and sauté for about 3 minutes or until cooked through. Transfer to a plate.
  6. Place peppers and onions in a 9-inch glass pie plate. Cover with vented plastic wrap, and microwave on high for 3 minutes or until soft.
  7. Add the onions and peppers to the pan; sauté for 3 minutes, or until lightly browned. Top pork mixture with peppers and onions.
  8. Line the pita pockets with the spinach. Add the pork mixture. Top each sandwich half with a tomato and some cucumber sauce.
