INGREDIENTS
1 1/2 pounds Sirloin Steak, Sliced Thin or Pre-Sliced Steak
1 tsp McCormick's Montreal Steak Seasoning (or similar)
Salt and pepper to taste
1 Cup Green Peppers, Sliced
1 Cup Mushrooms (optional, of course)
1 Cup Onion, Sliced
2 Garlic Cloves, Chopped or 2 tsp Minced Garlic from Jar
2 oz Cream Cheese
1 tsp Worcestershire Sauce
2 Eggs
1/2 Cup Heavy Whipping Cream
1/2 Cup Shredded Parmesan
4-5 Slices Provolone Cheese, Sliced into Pieces
DIRECTIONS
Preheat oven to 350 degrees
In a skillet, warm a splash of olive oil over medium heat.
Season steak with steak season, salt, and pepper.
Cook in the skillet for 2-3 minutes, flipping the steak strips to get it cooked on all sides.
Add green peppers, onions, garlic, and mushrooms to the same skillet. Cook until the vegetables have the desired softness. I prefer mine a little crisper than most.
When the veggies are cooked and the steak is no longer pink, drain any excess from the pan and discard.
Return to stove on low-medium heat and add the Worcestershire sauce and the cream cheese, stirring until the cream cheese is melted.
Remove from heat.
Mix the eggs, shredded parmesan cheese, and heavy cream in a bowl.
Next, spray your casserole dish, preferably 8x11, with cooking spray. Pour the steak mixture from the skillet into the casserole dish.
Drizzle the egg and cheese mixture over the top of the steak mixture.
Top with Provolone Cheese slices.
Bake until the cheese bubbles, usually about 15-20 minutes.
Cool and serve!
