🧊 Storage & Reheating
Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.

Cheese Lovers: Swap Parmesan for Pecorino Romano or Asiago.
Garlic Butter Bliss: Roast with extra garlic cloves for a bolder flavor.
Sweet & Savory: Drizzle with a touch of honey or maple syrup before serving.
Herb Swap: Use rosemary or thyme instead of Italian seasoning for a different flavor profile.
