- Mix the butter, green onions, parsley, thyme, salt, and black pepper until you have a paste. In a large, deep skillet, heat this mixture and add 3 tablespoons of olive oil.
- Place the steaks in the skillet and fry for 5 to 7 minutes on each side (or to your preferred doneness). Remove and set aside.
- In another skillet, heat the remaining olive oil and lightly sauté the garlic until it wilts. Add the mushrooms and sauté over high heat for five to ten minutes or until they wilt. Season with salt, pepper, and vinegar.
- Arrange the steaks on a serving platter and place the sautéed mushrooms around them. Garnish with tomatoes and rosemary sprigs. Serve with roasted potatoes or white rice.
