01 - In a large pot, bring water to a boil and add the Weisswurst. Reduce heat and simmer for about 20 minutes until cooked through.
02 - While the sausages are cooking, prepare the pretzel salad by combining pretzel pieces, red onion, cucumber, and cherry tomatoes in a large mixing bowl.
03 - In a small bowl, whisk together olive oil, apple cider vinegar, salt, and pepper. Pour the dressing over the pretzel salad and toss gently to combine.
04 - Once the Weisswurst is cooked, remove them from the pot and serve hot alongside sweet mustard and the prepared pretzel salad.
