Then line a baking sheet with parchment paper. Then spread the 12 triangular croissants into a circle on the baking sheet. Put a layer of cheese on top. Then you cover the ring with things you like, e.g. corn, paprika etc. in the ingredients are just examples.
You shouldn`t cover the ring too thickly. Finish with a layer of cheese, add herbs or spices as desired. Fold in the croissants and pour cheese over them again.
