Add a little bit of oil to frying pan and season hashbrowns with salt and pepper. Cook until done.
While hashbrowns are cooking in a separate frying pan cook your chorizo. Remove chorizo from it's casing and fry it up just like you would ground beef. When done turn off heat.
Add eggs directly to your chorizo, season with salt and pepper mix and cook on medium low heat until done.
Take tortilla and add a line of chorizo and eggs. Then a line of hashbrowns, and finally a handful of cheese. Roll into a burrito and wrap the burrito with aluminum foil. When done place your burrito's on a baking sheet in a 350 degree preheated oven for about 20 minutes.
