1 (14 ounce) can artichoke hearts, drained and chopped
1/2 cup mayonnaise
1/2 cup grated Parmesan cheese
1 teaspoon onion powder
1 teaspoon garlic powder
1/2 teaspoon pepper
1 (17.3 ounce) package frozen puff pastry
Instructions
Drain spinach well, pressing between layers of paper towels. Stir together spinach, artichoke hearts, and next 5 ingredients.
Thaw puff pastry at room temperature 30 minutes. Unfold pastry, and place on a lightly floured surface or heavy-duty plastic wrap. Spread 1/4 spinach mixture evenly over pastry sheet, leaving a 1/2 inch border. Roll up pastry, jellyroll fashion, pressing to seal seam; wrap in heavy-duty plastic wrap. Repeat procedure with remaining pastry and spinach mixture. Freeze for 30 minutes; cut into 1/2-inch-thick slices. (Rolls may be frozen up to 3 months.)
Bake at 400 degrees for 20 minutes or until golden brown.
