Preheat the oven to 350 degrees F.

Place the baguette slices onto a baking sheet and drizzle with olive oil. Toast bread until golden brown, approximately 6 to 8 minutes.

In a saute pan over medium-high heat, cook the bacon until crisp. Remove and let cool. In a mixing bowl, crunch the bacon, add peanuts and chopped cilantro.

Preheat a grill or a grill pan to high heat.

In a large bowl, whisk together the Italian seasoning, sage, salt, paprika, garlic powder, Scotch, and mustard. Add the steak to the bowl and coat it with the marinade. Marinate the steak for at least 15 minutes. Remove the steak from the marinade and grill until medium-rare, about 4 minutes on each side. Allow the steak to rest for a few minutes, then slice it thinly, against the grain.

To assemble the dish: Spread the crostini with creme fraiche, put the steak slices on the crostini, and top with a little of the bacon and peanut crunch.
