Ingredients:
- 1 lb Beef Ribeye or Sirloin, shaved ultra-thin
- 1 tbsp Neutral oil (Grapeseed or Avocado oil)
- 1 Large White Onion, thinly sliced
- 1 Large Green Bell Pepper, thinly sliced
- 1 tsp Kosher salt
- 0.5 tsp Coarse black pepper
- 4 Large Flour Tortillas (10-inch)
- 8 Slices Provolone Cheese
- 1 cup Shredded Monterey Jack cheese
- 2 tbsp Unsalted butter, softened
- 0.5 cup Mayonnaise
- 1 tbsp Prepared Horseradish
- 1 tsp Worcestershire sauce
- 0.5 tsp Garlic powder
Instructions:
- Prepare the dipping sauce by whisking mayonnaise, horseradish, Worcestershire sauce, and garlic powder in a small bowl. Refrigerate until serving.
- Set a large cast iron skillet over medium-high heat until wisps of smoke appear. Add neutral oil and the shaved beef in a single layer.
- Sear beef undisturbed for 2 minutes to develop a mahogany crust, then break up with a spatula and season with salt and black pepper. Remove beef and set aside.
- In the same skillet, sauté sliced onions and green peppers until moisture has evaporated and edges are charred. Remove and mix with the cooked beef.
- Wipe the skillet clean and reduce heat to medium. Spread softened butter on one side of each tortilla.
- Place one tortilla butter-side down in the skillet. Layer 1 slice of provolone, a quarter of the beef and pepper mixture, 1/4 cup shredded Monterey Jack, and a second slice of provolone.
- Fold the tortilla or top with another tortilla and press down. Grill for 2-3 minutes per side until the exterior is golden brown and the cheese acts as a binder. Repeat for remaining servings.
