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 ribeye steak and cook for 2–3 minutes until just browned. Remove steak from pan and set aside.
03 - In the same skillet, add green and red bell peppers along with yellow 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 - Combine shredded mozzarella and cream cheese in a microwave-safe bowl. Microwave in 30-second intervals, stirring in between, until melted and smooth. 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.
05 - Divide dough into 6 equal pieces. Roll each piece into a rectangle approximately 5x3 inches between two sheets of parchment paper.
06 - Place a slice of provolone cheese on each dough rectangle. Top with steak and pepper mixture, using about 2–3 tablespoons per roll. Carefully roll up each rectangle, pinching the seams to seal. Place seam-side down on the prepared baking sheet.
07 - Bake for 20–25 minutes, or until golden brown. Let cool for 5 minutes before serving.
