Prepare the shortcrust pastry: mix rice flour and pear margarine to obtain a sandy mixture.

Add salt and water to form a ball.

Remove the shortcrust pastry from the refrigerator and roll it out in a quiche/tart pan or directly on a baking sheet.

Cut the mozzarella (buffalo if lactose-free) into slices.

Alternate the slices of zucchini and mozzarella on the pastry.
