This recipe is from Food Network it was so easy and simple I had to share the delicious results. I would suggest you double the oil mixture if you like having a little dipping sauce.
3 tablespoons extra-virgin olive oil
1 tablespoon chopped fresh oregano
1/4 teaspoon red pepper flakes
1/2 baguette, halved lengthwise
1 large clove garlic, halved
1 medium tomato, halved and sliced 1/4 inch thick
Sliced provolone cheese
Preheat a grill to medium high. Combine the olive oil, oregano, red pepper flakes and a pinch of salt in a small bowl. Brush the cut sides of the baguette with some of the flavored oil. Grill cut-side down until toasted, about 4 minutes.
Rub the grilled sides of the baguette with the garlic. Top with the tomato slices, season with salt and cover with the provolone. Grill, covered, until the cheese melts, 3 to 5 minutes.
Drizzle with the remaining flavored oil and season with salt. Cut into pieces.
