Caramelizing is a delicious treatment for the often maligned Brussels sprout. The onion and vinegar add bite, while the pistachios add crunch.
These are absolutely melt in your mouth delicious! You can make them on the grill or in the oven. Even friends of ours that don’t care for onions loved these! I would recommend that you use 1 large onion for every 2 people. Some people want one whole onion to themselves so you might want to make some extra! They are also good heated up the next day but we rarely have any extra!
