Step 1: Trim and cut pork into 1 inch cubes. In large bowl, whisk together lemon juice, oil, garlic, oregano, salt and pepper. Add pork and stir to coat. Marinate for 10 minutes (make ahead: cover and refrigerate for up to 24 hours). evenly thread pork onto six 8 inch skewers; place on foil lined baking sheet.
Step 2: Brush with marinade. Broil 6 inches away from heat, turning halfway through, until just a hint of pink remains inside, about 12 minutes. Spread tzatziki over each pita.
