Caramelized onions are one of those ingredients that always manage to nudge a recipe up a few notches. While they can be a pain to make--especially if you make them the right way, without taking any shortcuts--the good news is that they can be made in advance and refrigerated or frozen for later. Put caramelized onions in everything!

So many great ideas here, but I have to place a shout out for a recipe from the Greens Cookbook that I have been making since 1994. It is the Carmelized onion, Goat Cheese and Sage frittata. It is topped with a balsamic vinegar reduction. It is an elegant crowd-pleaser at brunch. Haven't tried making it vegan, but I might add a potato instead or serve cashew cheese on the side.
oooh yes <3
