Steps
1. In a small saucepan, combine ketchup, BBQ American sauce, fresh orange juice, apple cider vinegar, water, sugar, salt, pepper, dried thyme, and bay leaf. Simmer gently for 10-15 minutes until slightly thickened, then remove bay leaf and set sauce aside.
2. Heat cooking oil in a pan over medium heat. Sauté sliced onions and red bell peppers until softened, about 5 minutes.
3. Add sliced pork to the pan and cook until browned and cooked through, about 6-8 minutes.
4. Pour half of the prepared BBQ sauce over the pork and vegetables, stir to coat and heat through.
5. Slice the bread roll and toast lightly if desired.
6. Spread a thin layer of remaining BBQ sauce on the bread.
7. Layer the cooked pork, onions, and bell peppers on the bread, then top with thin slices of green apple for a fresh crunch.
8. Close the sandwich and serve immediately.
