Preheat oven to 400°.
Spray 24 muffin tins very generously with olive oil cooking spray.
Combine one egg with hash browns, olive oil, 1 cup cheese and half each of the salt and pepper in a large mixing bowl.
Divide mixture evenly between 24 muffin tins and press down.
Sprinkle each muffin with parsley, rosemary and thyme.
Bake at 400° about 10-15 minutes or until potatoes are crispy.
Meanwhile, place sausage in a large skillet and cook over medium heat until no pink remains.
Mash the sausage down with a hamburger chopper while cooking to break the sausage into very small pieces.
When sausage is cooked through, remove sausage to a paper towel-lined plate to drain.
Meanwhile, whisk remaining 8 eggs in a large mixing bowl.
Add remaining 1 cup cheese, remaining ½ tsp. salt and ¼ tsp. pepper, cooked sausage, red and orange bell peppers and half-and-half or milk.
Stir to combine.
Pour egg-sausage mixture evenly over each potato muffin crust.
Sprinkle with additional salt, pepper, parsley, thyme and rosemary, if desired.
Bake an additional 10-15 minutes or until eggs are cooked through.
Allow muffins to cool in muffin tins about 5 minutes before removing.
Serve hot or lukewarm.
