What you are describing sounds like Wurstsalat. But usually it's eaten with bread (dark stone oven bread is best because the bitterness matches the vinegar and onions) and the dressing is only vinegar and oil.

Local versions are "Schweizer Wurstsalat" (Swiss sausage salad) where you add cheese like Swiss or mild mountain cheese and "Lumpe'supp / Lumpensuppe'" (rag soup) which is made with blood sausage and very strong cheese like Romadur.

The thing my mother is eating in the picture is exactly what you described (the bread is on the table). I called it salad dressing as a synonym for the vinegar and oil "sauce", since some herbs are in there as well.

Lumpensuppe is something different here. Its basically goulash soup with either sauerkraut or bacon and cream and bell pepper.
