Peel the potatoes, cook them and then let them cool. In the meantime, cut the cooked ham, Tyrolean bacon and onions into small pieces and fry them in a pan. Cut the cold potatoes into slices and fry them in batches in pans.
Put half of the potatoes, bacon and onions in a casserole dish, put the other half in a second casserole dish with some chopped peppers and fried mushrooms. Pour an egg-milk mixture (seasoned with salt, pepper, paprika and rosemary) over it and cook in the oven for about 40 minutes.
Meanwhile, use a hand blender to make remoulade sauce from egg yolks, mustard, vinegar, oil, salt and pepper. Then add the finely chopped onions, capers and gherkins and season with lemon juice.
Arrange the farmer's breakfast, a sliced gherkin and the remoulade sauce on a plate.
