Tomato Melts

This was a quick and oh-so-delicious impromptu lunch the other day and it would lend itself to so many variations!  The first batch (pictured here) were simply slices of tomato with provolone cheese melted on top in the broiler to a nice brown.  We later experimented with "pizza toppings" such as green olives and mushrooms, but this could also be faux-mexican (with taco meat and cilantro) or an open -faced version of many sandwiches, such as ham and swiss or a tuna melt.  There are just so many possibilities!
