Brown the sausage in a large iron skillet. Set aside.
In a large bowl, beat the eggs, milk and seasoned salt together.
Stir the remaining ingredients into the egg mixture. Save some cheese to sprinkle on the top.
Pour the egg mixture on top of the sausage.
Sprinkle the remaining cheese on the top.
Bake for 25-30 minutes or until the top is golden brown and a knife inserted near the center comes out clean.
Notes
You can use any kind of sausage, our favorite is Jimmy Dean's sage sausage. I've also made it with sweet potato before, diced into small cubes and mixed in with hot sausages and veggies before adding the egg mixture. Delish!
