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 just browned. Remove steak from pan and set aside.
03 - In the same skillet, add peppers and onion. Sauté for 4–5 minutes until softened. Return steak to the pan, stir in Worcestershire sauce, salt, and pepper. Cook for 1 more minute, then remove from heat and let cool slightly.
04 - In a microwave-safe bowl, combine shredded mozzarella and cream cheese. Microwave in 30-second intervals, stirring in between, until melted and smooth.
05 - Add almond flour, egg, baking powder, and garlic powder to the cheese mixture. Mix well until a dough forms. If sticky, chill in the fridge for 5 minutes.
06 - Divide dough into 6 equal pieces. Roll each piece into a rectangle (about 5x3 inches) between two sheets of parchment paper.
07 - Place a slice of provolone cheese on each dough rectangle. Top with steak and pepper mixture (about 2–3 tablespoons per roll).
08 - Carefully roll up each rectangle, pinching the seams to seal. Place seam-side down on the prepared baking sheet.
09 - Bake for 20–25 minutes, or until golden brown.
10 - Let cool for 5 minutes before serving.
