Heat your olive oil or butter in a large skillet

Once hot add mushrooms and onions keep at medium heat

When the onions turn translucent add the salt, pepper, and nutmeg at the same time as ground sausage. (I used sweet Italian) cook on high heat till browned.

While the meat is cooking press two pie crusts into two 9 inch round layer cake pans. Greased or sprayed with non-stick cooking spray

Once the bottom of the pan has begun to blacken deglase with a 1/4 cup milk mixing throughly. Remove from heat.

Once cooled for a few min, just long enough to thicken, devide meat mix in half and place on pie crusts

Beat half eggs in a bowl with half remaining milk until blended. Pour over meat mix in one crust.

Repeat step 7 for other pie

Devide cheddar and sprinkle over mix.

Devide Swiss and sprinkle over mix

Bake side by side for 40-45 min until brown on top and can be cut with a knife in the center

Cool for 5 min before eating
