Preheat an oven to 400F and spray an 8x8 baking dish or pie pan with nonstick cooking spray. Set aside.
In a large skillet, cook the ground beef and sausage over medium-high heat.
Mix the chorizo seasoning in a small bowl before adding to the meat as it continues cooking.
Once no pink remains in the meat mixture, reduce to a medium heat and add the egg whites. Cook until the egg whites are no longer runny.
Remove the meat and egg whites from the heat before adding the Greek yogurt. Stir to fully incorporate. Set aside.
Add the crescent rolls to the baking dish. Make sure the dough goes at least an inch up the side of the dish, ideally more. And press the dough together to ensure no cracks remain in the bottom of the dish.
Add 1/2 the cheese on top of the dough before adding the meat and eggs mixture. Top with remaining cheese.
Bake for 14-16 minutes or until the crescent roll edges are golden brown. Let the breakfast casserole slightly cool before serving. (Cooling for 30 minutes is ideal.) Refrigerate leftovers.
