Preheat the oven to 350 degrees and line a large baking sheet with foil.
Start by preparing the crostini. Fill a shallow dish with about a quarter inch of olive oil, then stir in minced garlic and sea salt to combine. Working in batches, place the baguette slices in the olive oil and gently press down to let them soak. Flip and press down gently again, then transfer crostini to the prepared baking sheet.*
Bake crostini for 6 minutes or until bottoms are slightly crisped. Then flip each crostini over and bake for another 6 minutes, or until bottoms are lightly toasted.
Next, prepare the bruschetta. Combine diced tomatoes, onion, garlic, and olive oil in a medium bowl. Stir well to combine, then season with sea salt to taste. Set aside.
To plate this appetizer, spread about 1 tsp of garlic & herb cheese onto each crostini. Top crostini with a spoonful of fresh bruschetta and serve immediately.
