Tips
Start with less Worcestershire sauce as noted in source and adjust to taste for preferred saltiness.
Cooking patties and vegetables in separate skillets allows better control over doneness of each component.
Good to Know
Cooked patties refrigerate up to 3 days. Reheat gently in skillet or oven to avoid drying meat.
Mix and form patties up to 24 hours ahead; cover and refrigerate. Sauté vegetables up to 4 hours ahead and store separately.
Serve immediately while cheese is melted and vegetables are warm. Pairs well with rice, mashed potatoes, or simple salad.
Common Mistakes
Do not skip covering the skillet at the end; uncovered cheese will not melt evenly.
Do not overmix the meat mixture; this toughens the patties.
Do not add cheese before patties reach desired doneness; it will cook unevenly.
