Trim the thick outer fat from the pork and cut the meat into 2.5-3 cm cubes.
Whisk the olive oil, lemon juice, crushed garlic, oregano and pepper in a bowl, add the pork and mix well.
Cover and marinate in the refrigerator for at least 2 hours or overnight. If you use wooden skewers, soak them in water for 30 minutes.
Thread the pork onto 12 skewers, leaving small gaps between the pieces, and season with the salt.
Heat a charcoal grill or grill pan to high heat.
Grill the skewers for 10-12 minutes, turning every 2-3 minutes, until browned outside and 63C in the center.
Squeeze lemon over the skewers and serve hot, with pita, tomato and tzatziki if you like.
