01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Heat olive oil in a large skillet over medium-high heat. Add sliced steak and cook for 2–3 minutes until browned. Remove from pan and set aside.
03 - Add peppers and onion to the same skillet. Sauté for 4–5 minutes until softened.
04 - Return steak to the pan. Stir in Worcestershire sauce, salt, and pepper. Cook for 1 minute, then remove from heat and let cool slightly.
05 - In a microwave-safe bowl, combine shredded mozzarella and cream cheese. Microwave in 30-second intervals, stirring between, until melted and smooth.
06 - Add almond flour, egg, baking powder, and garlic powder to the cheese mixture. Mix until dough forms. If sticky, refrigerate for 5 minutes.
07 - Divide dough into 6 equal pieces. Roll each into a 5x3 inch rectangle between two sheets of parchment paper.
08 - Place a slice of provolone on each dough rectangle. Top with 2–3 tablespoons of steak and pepper mixture.
09 - Carefully roll up each rectangle, pinching seams to seal. Place seam-side down on the prepared baking sheet.
10 - Bake for 20–25 minutes until golden brown. Let cool for 5 minutes before serving.
