Let the strudel dough rest at room temperature for 15-20 minutes. Soak the toast. Defrost peas, drain corn. Grease the hollows of a muffin tray (12 hollows).
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Whisk 1 egg and milk. Unfold 1 pastry sheet and spread thinly. Cut into 12 pieces. Place 1 piece each in a muffin tray.
Knock corners inwards. Spread the rest of the dough sheets in the same way, cut them into pieces and place them staggered on the first pieces. Turn the corners over.
Peel and finely chop the onion. Knead with minced meat, 1 egg, tomato paste and well squeezed toast. Season with salt and cayenne pepper.
Wash and quarter the tomatoes. Knead with peas and corn under the mince. Spread the mixture evenly in the bowls. Bake in a hot oven for 25-30 minutes. Serve sprinkled with oregano.
