Meatloaf Sandwich

Bahan-bahan (4 porsi)

• 4 slices leftover meatloaf (see Turkey Meatloaf for a great recipe)
• Nonstick spray (canola oil, or additional butter)

• 1/4 cup buttery spread ( or softened butter)
• 4 slices provolone cheese ( cheddar cheese, or your cheese of choice)
• Sliced tomato
