Tips & Variations

• Ingredient substitutions: If you’re looking for a lighter option, you can use ground turkey or chicken instead of beef. For a vegetarian option, substitute diced mushrooms or plant-based ground meat.
• Optional variations: Add some sautéed bell peppers for extra flavor or a splash of hot sauce for a kick of heat. You can also use different cheeses, like provolone or cheddar, if Swiss isn’t available.
• Storage or reheating tips: Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm gently on the stovetop or in the microwave, adding a little water to keep the mixture moist.
