Your favorite recipes with caramelized onions?
Besides french onion soup?
Sister is moving into her first apartment sans college roommates this week, and I have a ton of caramelized onions saved in the freezer. I'd like to use that to make something warm and filling to give to her and her new home. I'm thinking a quiche, but I'm definitely open. Extra points if the dish can easily be frozen for the future as she's always very busy!
