Slice the baguette on the bias into ½" thick slices. You’ll use approximately ½ oz of meat per slice of bread (a 6 oz steak requires 12 slices of bread). Brush or drizzle both sides of each piece of bread with olive oil and set aside.
Place a skillet over medium heat. Once the skillet is hot, grill the bread slices until golden brown on each side—approximately 2–3 minutes per side. Remove from skillet and set aside to cool.
Slice the cooled steak into very thin strips and set aside. Drizzle each toasted bread slice with just a bit (¼–½ tsp) of balsamic vinegar and stack about ½ oz of the thinly sliced steak on top.
Sprinkle blue cheese crumbles over the steak then top with several leaves of baby arugula. Drizzle a couple of drops of extra virgin olive oil over the top of each bruschetta and season with coarse salt and fresh cracked pepper.
Serve immediately. Enjoy!
