Cut the pork into 1-inch cubes and toss with the oil, juice of 1 lemon, 2 minced garlic cloves, oregano, salt and pepper; let sit 10 minutes.
For tzatziki, grate half the cucumber, squeeze it dry, and stir into the yogurt with the remaining garlic, a squeeze of lemon and salt.
Thread the pork onto skewers (soak wooden ones in water for 10 minutes first).
Grill or broil on high 10-12 minutes, turning, until charred and 145°F.
Warm the pitas and serve with the skewers, sliced tomatoes, onion, the rest of the cucumber and tzatziki; kids can roll theirs up like a wrap.
