Prepare a marinade by combining lemon juice, olive oil, oregano, garlic, salt, and pepper in a bowl.
2 tablespoon lemon juice, 1 teaspoon olive oil, 1 teaspoon dried oregano, 1 garlic clove, Sea salt and freshly ground black pepper
Pound the pork medallions between plastic wrap until they are roughly 1 inch thick.

Create a filling by mixing tomatoes, pine nuts, oregano, garlic, and lemon zest in a separate bowl.

Add the filling to half of the pork medallions and fold the remaining half over. Tie the medallions with twine.
Place the stuffed pork medallions in a baking dish and cover with the marinade. Marinate for 30 minutes in the fridge.
Heat a frying pan, adding cooking fat. Cook the pork medallions for approximately 5 minutes on each side, setting aside once fully cooked.
