Preheat oven to 400⁰. Spray mini muffin tins with cooking spray. Chop artichoke hearts into large pieces, add remaining ingredients and mix well. Using a 2 ½ inch round cookie cutter, cut each sheet of puff pastry into 15-20 circles.
Press the circles into prepared mini muffin tins. Fill with artichoke filling. Bake for 20 minutes, or until golden brown.
