Roll out the puff pastry sheet over parchment paper.
Spread the basil pesto evenly on top of the puff pastry, using a spoon or spatula.
Sprinkle the grated Thomasville Tomme on top of the pesto.
With a knife or wheel cutter, cut the puff pastry into strips about 1 inch.
Fold the strips to make a Christmas tree shape. You can leave the puff pastry as is or add a skewer in the middle to help keep shape (this part is optional)
Bake the trees for 10-15 minutes or until golden brown.
