Slow Cooker Greek Gyros with Crispy Pork

0 Make tzatziki (can be done up to a week ahead, and is better after at least a night in the fridge)Grate cucumber and sprinkle with salt. Let sit for 5 minutes and then squeeze out as much liquid as possible. (I like to do this by placing the shredded cucumber on a clean dish towel and wringing it out over the sink. You can also just pat the cucumber really well with paper towels). Combine cucumber with yogurt, lemon juice, garlic powder and dill. Refrigerate until ready to serve.
1 Combine tomato, cucumber, parsley and olive oil. Season with some salt and pepper.
2 Warm wraps / pita rounds according to package directions (in the microwave or wrapped in foil in the oven).
3 Reheat pork, if made ahead.
4 Assemble wraps by filling wraps / pita rounds with tzatziki, pork, red onions, tomatoes and cucumbers.
