Preheat oven to 375 degrees. Line a rimmed cookie sheet with parchment paper. Unroll the crescent roll dough on top of the parchment paper, lining up the edges and sealing with your fingers. Push the dough against the sides of the pan to make a bit of crust to hold in all the toppings.

Cook the chorizo with the diced onion in a large skillet over medium high heat, breaking up the meat as it cooks for about 8 minutes. Sprinkle the cooked chorizo over the top of the crescent dough.

In a medium sized bowl, beat together the eggs, milk, and salt and pepper. Pour in the center of the pan over the chorizo and crescent dough, allowing it to run to the edges of the pan. You may need to turn the pan a bit to get the eggs evenly distributed. Try to avoid pouring the eggs directly around the edges because it may leak over the crust and you want to keep it contained! Sprinkle the top with the shredded cheese.

Bake in the preheated oven for 25-30 minutes until crust is golden brown and filling is set. Slice and serve with the toppings. Enjoy!
