Preheat the oven to 350 degrees F.
Add the sausage and chorizo to a large cast iron skillet over medium heat. Cook until browned, stirring occasionally, about 10 minutes. Stir in the bell pepper, jalapeno and onion and cook for about 5 minutes, stirring occasionally.
In a small bowl, whisk the egg and cream corn together. Stir in 1 sleeve of the Ritz crackers.
Spread the cracker mixture over the top of the sausage mixture. Place the butter slices evenly on top and bake for about 25 minutes.
Remove the dish from the oven and turn the oven temperature to 400 degrees F.
Top the dish with the remaining sleeve of Ritz crackers. Cook for about 10 minutes, sprinkle the top evenly with cheese and bake for another 4 to 5 minutes, or until the cheese has melted. Remove from the oven and top green onions. Serve hot.
