3/4 cup grated Parmesan
Zest of 1 lemon
1 tablespoon finely chopped fresh parsley
1 large egg
Flour, for dusting
1 sheet frozen puff pastry (from a 17.3-ounce package), thawed
About 40 pimento-stuffed green olives (two 3-ounce jars), drained
Wrapped olives can be frozen in a single layer not touching one another and stored in an airtight container for up to a month before baking. When baking, they can go straight from the freezer to the oven.
