Balsamic Marinated Flank Steak with Sauteed Tomatoes and Spinach Recipe

We absolutely love bruschetta as an appetizer, but as a main dish, it definitely is a little lacking in the protein department. For dinner one night, we wanted to try and get the flavors of balsamic vinegar, fresh tomatoes, and mozzarella into one dish couple with a shareable steak. After a little bit of thinking, we came up with this recipe that features a marinated and sliced flank steak combined with sauted tomatoes and spinach, as well as fresh mozzarella on top. This is dish is brightly flavored, and absolutely perfect for al fresco dining during the summer. If you have fresh tomatoes or greens from your garden, it'll make the flavors even more intense, as well as making the meal a bit more special. We wanted to enjoy this meal carb free (we had stocked up on birthday cake the previous night, and yes, we know there are carbs in vinegar), so we didn't want pair this with any carbs. If you're feeling some carbs, this meal would be amazing with some toasted italian bread to dip in the juices from the beef and tomatoes. Mmmm What do you think of this recipe?
