Put both flours, milk, eggs, a pinch of salt and a tablespoon of olive oil in a bowl and stir well with a whisk. Let the pancake batter rise for 10 minutes.
Drain a can of tuna in its own juice. Put the tuna in a small bowl and chop with a fork. Now add a tablespoon of sour cream and 4 tablespoons of yoghurt to the bowl and stir well (you can also use a hand blender to chop the tuna). Season the tuna paste with salt, pepper and a little chili powder.
Put a little olive oil in the pan and fry the pancakes in portions until golden brown. Let the pancakes cool.
Cut the bell pepper into strips. Pluck 8 leaves of iceberg lettuce and wash well.
Brush the cooled pancakes with the tuna paste. Then put on a sheet of lettuce and strips of pepper. Then roll up the pancakes carefully, but still reasonably firm.
If you don`t eat them right away, wrap them in cling film and store in the refrigerator.
