Preheat oven to 400° F. Spray the baking sheet with cooking spray.
Place baguette slices on the prepared baking sheet.
Place olives, cream cheese and blue cheese in the bowl of your food processor and puree until smooth.
Spread the olive-cheese mixture on top of each baguette slice.
Bake for 5 minutes or so, just until cheese is bubbly and beginning to brown. Keep your eye on them, so you don’t over bake them!
Garnish each crostini with one half olive and dust with paprika. *Paprika is totally optional!
