Chorizo Breakfast Pizzas

So we found a recipe for breakfast pizzas in our Flour, Too cookbook, but we didn't want to make them the way the recipe said :).  Instead, we made them using Flour's brioche recipe, which can be found here, or more easily here.  Anyway, I used half of this batch and made 8 pizzas out of this.  Each pizza was 530 calories, approximately, and Aaron gave this a perfect 10, Noah and I gave this a 9, and Owen gave it an 8 because he doesn't like chorizo :).  Here's what we did:

1/2 batch of Vicki's breakfast burrito meat, minus the egg (chorizo and potatoes)
2 onions, sliced very thinly
2 T butter
salt and pepper to taste
1 egg
1/2 batch of brioche
1/4 c sour cream, divided (we used a little less)
2 oz grated Monterey Jack cheese

Toppings of choice, we used avocados and tomatoes

Follow the directions for the brioche, and after proofing it overnight, begin making the pizzas.
Preheat the oven to 350.
Melt the butter in a pan, and caramelize the onions for about 30 minutes, seasoning well.
Cook the chorizo and potatoes with the caramelized onions and the egg.
Cut the brioche into 8 segments, then shape them into circles with a rim, like little mini pizzas.  Cook for 10 minutes on parchment covered cookie sheets.  Remove the brioche from the oven, then place around 1 T of sour cream in the bottom (or less) of the brioche, then top with the chorizo mixture.  Top with grated cheese, and cook for about 20 minutes, keeping an eye on them so they don't over bake.  Serve hot.
