Drizzle the ribs with olive oil and season with salt and pepper. Allow them to marinate for 2 hours or overnight by covering them with plastic wrap and placing them in the refrigerator. Before cooking, remove them from the fridge to reach room temperature.
Prepare the chimichurri sauce by combining all the sauce ingredients in a bowl and mixing them. Set it aside until the ribs are ready to be cooked.
Heat a grill pan over the fire or prepare the coals. Cook the ribs for 8-10 minutes on a medium-hot pan or over the coals until they are golden brown on both sides.
Serve the ribs hot, topped with some of the spicy chimichurri sauce, drawing inspiration from Argentine cuisine.
