How to Make It
Light a grill. In a medium bowl, blend the ricotta cheese with the minced garlic and chopped oregano and season with salt and pepper.
Grill the baguette slices over a medium-hot fire without turning until golden brown, about 20 seconds. Lightly rub the grilled side of each toast with the whole garlic clove and top with the ricotta mixture and an anchovy fillet.
Return the crostini to the grill, anchovy side up. Cover and cook the crostini until the ricotta is hot, about 2 minutes. Transfer the crostini to a platter, drizzle with olive oil and serve.
