Use a pizza cutter to slice the pie crusts into thin strips.
Weave eight of the pie strips together to form a "basket."
Top the strips with ham and cheese.
Close up the basket by folding over the strips and pinching them together with your fingers. You can cut off any excess strips. This layer won't be as pretty, but that's ok since it's the bottom.
Flip the baskets over and transfer them to a baking sheet.
Coat with melted butter and sprinkle poppy seeds on top.
Bake for 15-minutes, let them cool for about five minutes and then cut the excess cheese off the edges to clean them up.
