Place the puff pastry slices next to each other and defrost. Halve, clean and wash the peppers. Cut the paprika halves into small cubes. Drain the corn in a sieve. Grate cheese.
Mix mustard, milk and eggs and season with salt, pepper and nutmeg. Wash marjoram, shake dry and finely chop the leaves of 5 stalks. Mix half the cheese, chopped marjoram, paprika and corn. Place the puff pastry slices on top of each other and roll out 1-2 mm thin on a floured work surface. Cut out circles (approx. 11 cm Ø). Lay the remaining dough on top of each other (do not knead) and roll out again and cut out a total of 12 circles. Grease the hollows of a muffin tray and line them with the dough. Press the protruding edges inwards. Sprinkle the dough with breadcrumbs. Pour in the vegetables, pour over the egg milk and bake in a preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) for 20-25 minutes until golden brown.
