Truffle Eggs on Caramelized Onion Nests

Don't eat boring breakfast if you can at all help it. This will help: 


Yet another decadent meal produced by my favorite (and only) mom-in-law, Debbie. She can do no wrong, so you know this is going to be delicious.
2 large onions - thinly sliced
Butter or duck fat
Truffle salt.
Pepper
2-4 Eggs ( how hungry are you? )
Sherry vinegar or your favorite white balsamic
Optional- grated smoked Gouda Cheese
For the onions:
Melt about 3 tablespoons fat in a cast iron skillet. Add the sliced onions some of the salt and pepper. Let the onions slowly caramelize, moving them around in the pan occasionally ( you can speed this up a little if you cover them for a bit ).





When the onions are fully done transfer to a bowl and keep them warm. Add a little more fat to the skillet and cook eggs till top is almost set. ( You will want them loose; they will be like a sauce for the onions). On a plate form a nest shape out of the onions, please eggs in center. Deglaze the pan with the vinegar and pour this over the eggs. Sprinkle more truffle salt and some pepper on the eggs. If using Gouda cheese, add about a tablespoon grated on top. Serve with Renee's Pao de Queijo (see recipe earlier in the month of January 2015) and fruit.
