Roll up the shortcrust pastry and cut out circles with a glass (diameter approx. 4 - 5 cm). Line a silicone mold with small indentations with the dough. Mix all other ingredients in the blender.
Pour into the prepared dish and sprinkle a little gratin cheese over it. Bake at 200 ° C for about 15-20 minutes.
Very good as finger food or as a small starter with salad.
