Ingredients You’ll Need
To get the best results, use fresh vegetables and high-quality beef. The combination of different colored peppers not only adds visual appeal but a subtle range of sweetness.
-
1.5 lbs Ground Beef: You can also use thinly sliced ribeye or sirloin for a more traditional texture.
-
2 Large Bell Peppers: A mix of green, red, and yellow provides the best flavor profile.
-
1 Medium Yellow Onion: Sliced into thin strips.
-
8 oz Mushrooms: Sliced (Cremini or Button work great).
-
2 Cloves Garlic: Minced.
-
1 tbsp Worcestershire Sauce: Adds that essential savory depth.
-
1 tsp Smoked Paprika: For a hint of wood-fired flavor.
-
Salt and Black Pepper: To taste.
-
2 tbsp Olive Oil or Butter: For sautéing.
-
8 oz Provolone Cheese: Sliced or shredded (Provolone is the authentic choice, but Mozzarella works too).
-
4 oz Cream Cheese: Softened (this creates a “hidden” creamy sauce layer).
