Heat olive oil in a skillet over medium heat.
Add the sliced onion and bell pepper to the skillet, sautéing until soft.
Season the beef with salt, pepper, and Worcestershire sauce before adding to the skillet.
Cook the beef until browned and just cooked through, about 3-4 minutes.
Remove from heat and let cool slightly.
Place the tortilla on a flat surface and layer the beef mixture and cheese evenly.
Roll the tortilla tightly, enclosing all the filling.
Slice the rolled tortilla into pinwheels, about 1 inch thick.
Place the pinwheels on a baking sheet lined with parchment paper.
Bake in a preheated oven at 400°F (200°C) for 10-12 minutes until golden brown.
Serve immediately with your favorite dipping sauce.
