OK...I'm probably in the minority because I LOVE baby brussel sprouts, but here's a recipe I just tried that made even my husband like them.
In a large frying pan, cook 5-6 slices of bacon until crispy. Remove cooked bacon and drain on paper toweling. Slice one small onion into super thin rings and toss it into the bacon grease leftover in the pan. Cook and stir until it's soft, then dump in well-drained, cooked baby brussel sprouts.
In a small bowl, mix 1/2 cup of water, 1 TBLS. dijon mustard, and 2 TBLS. apple cider vinegar...pour it over the brussel sprouts, stir...toss in bacon. Let sautee a bit until most of the liquid has evaporated. Serve. YUM!
