Sauté the Vegetables and Beef:
In a medium skillet over medium heat, melt the butter.
Add asparagus, green bell pepper, and onion. Cook, stirring occasionally, until tender, about 5 minutes.
Stir in the diced beef sausage or ham and cook for an additional 2 minutes until heated through.
Prepare the Egg Mixture:
In a bowl, whisk together the eggs, salt, and black pepper until smooth.
Cook the Omelet:
Pour the egg mixture over the vegetable and beef mixture in the skillet.
Let it cook undisturbed for 2 minutes until the edges start to set. Gently lift edges with a spatula to allow uncooked eggs to flow underneath.
Add the Cheese:
Sprinkle the grated Provolone evenly over the omelet once the eggs are mostly set.
Fold and Serve:
Carefully fold the omelet in half and cook for another minute to melt the cheese thoroughly.
Slide onto a plate and serve warm.
