For the bacon snails first prepare the dough. For the dough, dissolve the yeast in lukewarm water, knead with flour, oil and spices and let rise in a warm place (30 minutes).
For the filling, roast the finely chopped onion and the diced bacon, as well as diced paprika in oil and season to taste. After resting, roll out the dough 1/2 cm thick and sprinkle the filling on it.
Roll up the dough with filling and cut down 2 cm thick slices. Press flat on a wide baking sheet and brush with egg. Preheat the oven to 220 °C and bake for 15-20 minutes.
