Slice the baguette into 1/2-inch slices and brush each slice (on both sides) with olive oil. (For reference, I had about 18 slices total).
Grill or bake the baguette slices. If baking, bake at 360°F (180°C) for about 10-12 minutes. I used an electric grill.
Mix the cream cheese and goat cheese together.
Once the bread is toasted, spread about 1 tsp of the cheese on top of each slice and spread it.
Add some fig jam (about 2/3 tsp on top of each slice) and spread it.
Top with a couple of leaves of arugula and a drop or two of lemon juice on each crostini.
