For the mustard sauce, peel the shallot and cut into fine cubes. Heat 1 tablespoon of oil in a saucepan. Sauté the shallot until transparent. Peel the mango and cut the flesh into fine cubes.
Add the mango to the shallot and sauté briefly. Remove from heat and stir in mustard. For the vinaigrette, whisk vinegar, salt, pepper and honey. Add 2 tablespoons of oil drop by drop.
Clean, wash and cut the lettuce into fine strips from the stalk. Spread a thin layer of oil on the grill pan. Grill the sausage for about 10 minutes while turning. Cut the bread roll into french fries-like strips.
Heat the fat in a frying pan and fry the bread roll strips for approx. 4 minutes while turning them until crispy. Mix salad and vinaigrette. Arrange salad, sprouts, sausage, mustard sauce and chips on plates.
