Prepare a vinaigrette with the vinegar, olive oil, mustard, sugar, and a pinch of salt and pepper.
Cook the brussel sprouts using your favorite method. Once again I just boiled them for about 12 minutes in salt water.
Drain the sprouts and put them in a salad bowl. Pour the vinaigrette on top and mix to coat. Let sit for 10 minutes and serve warm.
