Keto Philly Cheesesteak Casserole

Start by preheating the oven to 350°F and greasing a baking dish (I used a 9×10-inch one) with butter or cooking spray.
Cut the steak into thin slices and add it to a skillet over medium-high heat. Add the black pepper, salt, and steak seasoning, and cook for about 3 minutes, flipping halfway through.
Add the chopped onions, green peppers, mushrooms, and garlic. Cook for a few minutes until the vegetables are soft. Drain any excess fat (very important!).
Add the cream cheese and Worcestershire sauce, and cook until the cream cheese melts. Then, remove the skillet from heat.
In a medium bowl, combine the parmesan, eggs, and heavy cream.
Pour the steak mixture into the prepared dish and drizzle the cheese and egg mixture on top. Then, top with provolone slices and bake for about 20 minutes or until the cheese is bubbly. Enjoy!
