Rib Of Beef With Tomatoes And Garlic

6 slices rib of beef, each weighing about 250 g
3 tablespoons olive oil
3 garlic cloves, crushed
6 very ripe tomatoes, skinned, seeded, drained and chopped
1 tablespoon chopped fresh oregano, or 1 teaspoon dried oregano
Salt and freshly ground pepper

Heat the oil in a heavy frying pan over a high heat. When the oil is hot, quickly brown the beef slices on both sides. Do not crowd the slices. Cook only 2 at a time if necessary. Transfer the slices to a hot serving platter and keep them warm. Reduce the heat to medium. Add the garlic to the oil remaining in the pan, cook until golden, add the tomatoes and oregano, season with salt and pepper, and cook for 8 minutes. Return the slices of beef to the pan for 1 minute, or just long enough to heat them through thoroughly. Arrange the beef slices on a platter and serve them coated with the sauce.
