Ingredients
Method
- Heat oil in pan until smoking, then sear beef in batches until browned (~5 min).
- Push beef aside, add butter and then onions + peppers; caramelize (~6 min).
- Drain fat, stir in ketchup, Worcestershire, broth‑cornstarch slurry; simmer 3–4 min.
- Remove from heat, stir in chopped cheese until melted.
- Toast buns, top with cheese slice, spoon sloppy mixture onto buns; serve hot.
Notes
Sear in batches to keep pan hot; add broth when reheating to revive sauce.
