If you don't have balsamic glaze, take your balsamic vinegar and add it to a pot. Turn heat to high until the balsamic vinegar starts to bubble. When it bubbles, turn heat to low and let it cook. When the water evaporates and it turns into a glaze, take it off of the heat.
Take your tomatoes, garlic, capers, basil, and crushed red pepper flakes and mix them up in a bowl. Add salt and black pepper per taste.
Take your bread and brush olive oil on both side. Place it in the toaster or on a grill to toast up.
Add your parmesan cheese to the tomato mixture, and scoop on a generous amount onto each slice of bread.
Drizzle with balsamic glaze, and extra basil if desired!
