Cut the bacon into small cubes. Peel onions and cut into fine rings. Clean, halve and wash the peppers and cut them into fine slices. Fry bacon in a pan until crispy.
Add paprika and onion rings and fry briefly. Leave to cool. Mix the dough mixture and 1/4 litre lukewarm water with the dough hooks of the hand mixer to a smooth dough. Roll out on a greased baking tray so that a small rim is formed.
Spread the vegetable-bacon mixture on the dough. Wash the thyme, dab dry and pluck the leaves from the stalks. Whisk eggs and sour cream. Season to taste with salt and pepper. Add the thyme leaves, except some for garnishing.
Spread the egg cream on the vegetables. Sprinkle with grated cheese and bake in a preheated oven (electric: 175 °C/ gas: level 2) for 50 minutes. Allow to cool slightly and serve sprinkled with remaining thyme leaves.
