Let your onions express their true onioniness and do what they were meant to do. Here are two delicious ways to prepare onions before adding them to a dish. We swear -- it's totally worth the trouble!
1. Cook chopped onions in butter or oil until they're soft and golden. You can do this along with garlic and peppers as long as everything is chopped about the same size.
2. Cook thinly-sliced onions with a little bit of water over low heat for about 30 minutes. Keep adding water as it evaporates. Eventually you'll end up with super-sweet, golden-brown onions. And YES! You can do this with a Crock-Pot.
