Preheat the oven to 375 degrees.
Chop the onion and add it to a saute pan with a little olive oil over medium heat. Add the chorizo and crumble until the meat is cooked completely through. Transfer to a bowl.
Add a little bit more olive oil to the pan, turn up the heat and add the hash browns. Cook until browned and add to the bowl with the chorizo and onion.
Add cheese, salt and pepper, and red pepper flakes if you want it really spicy.
Cut the red peppers lengthwise and clean out the seeds. Arrange in a nonstick or lightly greased pyrex dish.
Fill each pepper with the cheese, chorizo, hash brown mixture. Top with extra cheese and bake for 25-30 minutes.
When the peppers are almost done, fry the eggs for whoever wants one.
Place one egg on top of each pepper and season with salt and pepper. Enjoy!
