Step 1: Melt Cheeses: In a microwave-safe bowl, combine 1 ½ cups of shredded mozzarella cheese with ½ cup of cream cheese. Microwave in 30-second intervals until smooth.

Step 2: Combine Ingredients: Allow the melted cheeses to cool slightly, then mix in 1 large egg until fully incorporated.

Step 3: Prepare Dry Mix: In a separate bowl, whisk together 1 ½ cups of almond flour, ¼ cup of coconut flour, baking powder, garlic powder, onion powder, and salt.

Step 4: Form Dough: Gradually add dry mix to melted cheese mixture, stirring until a soft dough forms. Knead gently until smooth.

Step 5: Rest Dough: Wrap in plastic wrap and let rest at room temperature for 5-10 minutes.

Step 6: Slice Steak: Thinly slice steak against the grain for maximum tenderness.

Step 7: Sauté Vegetables: Heat olive oil in a skillet, sauté onion and bell pepper until softened, then add mushrooms and cook until tender.

Step 8: Cook Steak: Add sliced steak to the skillet, season, and cook just until browned, stirring frequently.

Step 9: Preheat Oven: Preheat oven to 350°F (175°C) and prepare a baking sheet with parchment paper.

Step 10: Roll Dough: Roll out the dough between parchment paper into 12x16 inches.

Step 11: Fill & Assemble: Spread steak mixture on dough, layer provolone cheese, and roll tightly. Seal edges.

Step 12: Slice & Bake: Slice into 1-inch pieces and bake for 15-20 minutes until golden brown.

Step 13: Cool & Serve: Let cool slightly, garnish, and serve warm with dipping sauce.
