Preheat your oven to 200°C (400°F).
Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat. Add the sliced beef sirloin and cook until browned, about 4-5 minutes. Remove the beef from the skillet and set aside.
In the same skillet, add the remaining 1 tablespoon of vegetable oil. Add the sliced onions, green bell peppers, and mushrooms. Sauté until the vegetables are soft and slightly caramelized, about 5-7 minutes.
Return the cooked beef to the skillet and stir to combine with the vegetables. Season with salt and pepper to taste. Remove from heat.
Roll out the pie crust and fit it into a 9-inch pie dish. Trim any excess dough from the edges.
Spoon the beef and vegetable mixture evenly into the pie crust.
Sprinkle the provolone cheese evenly over the top of the filling.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and the crust is golden brown.
Remove from the oven and let the pie cool for 5 minutes before slicing and serving.
