Mix milk, 1 pinch of salt and flour in a bowl. Let the dough swell for about 10 minutes. Heat the oil in a coated pan (26 cm Ø). Pour in the dough and bake a pancake in approx. 4 minutes, turning it, take it out and let it cool down.
Rinse the beans, drain in a sieve. Clean the salad, wash and drain thoroughly. Clean, wash and dice the peppers. Peel and halve the onion and cut into thin strips.
Mix yoghurt and herb mixture. Season to taste with salt and pepper.
Place the pancakes on the work surface and spread with yoghurt-herb mixture. Spread beans, salad, onion and paprika evenly on top. Leave a small rim around the pancake. Fold the left and right edges about 3 cm to the middle.
Roll up the wrap, cut in half diagonally and arrange on a plate. Sprinkle with pepper.
