  • To start this St. Patrick’s Day appetizer, you’ll need to preheat your oven to 450°. Then line a baking sheet with parchment paper or foil for an easy cleanup later.

  • Cut your entire baguette into slices. About ½ an inch wide per slice. 

  • Place the slices in a single layer onto your baking sheet. Then lightly brush both sides of each piece with olive oil (this will use about 2-3 tablespoons of oil). 

  • Place the baking sheet in the oven on the top rack for about 5-10 minutes, or until the slices are golden brown and crisp on the top. 

  • While the bread is cooking, cut each tomato in halves or quarters depending on your preference. 

  • Add the chopped tomatoes into a bowl along with the mozzarella pearls and toss the Mozzarella and tomatoes with a good drizzle of olive oil until evenly coated. Then add salt and pepper to taste. 

  • When the crostini are done toasting, take them out of the oven and spread a thin layer of pesto onto each slice 

  • Top the pesto crostini with the mozzarella and tomato mixture. 

  • Add fresh basil to each crostini.
