Gluten Free Crumb Topping for Pies

When I make potted pies for my family I always used frozen sheets of puff pastry for the top. Now being gluten free I either use mashed potato or breadcrumb topping. Here's my version of the crumb topping. You can easily vary the amounts to suit your taste or use a different cheese. I usually make breadcrumbs out of GF bread that is becoming stale and freeze them for future use. The pie in the photo I am posting was heated for 30 minutes at 200C....for a longer period of time use a lower temp. The topping can also be placed under the griller to brown over an already cooked pie filling.
