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