Tips for the Perfect Philly Cheesesteak Casserole

• Meat Choice: Ribeye offers the best flavor and tenderness, but sirloin is leaner and works well too.
• Cheese Options: Provolone is traditional, but you can also mix in cheddar for extra sharpness.
• Vegetables: You can use a mix of colored bell peppers for visual appeal.
• Make-Ahead: This casserole can be assembled a day ahead and baked just before serving.
