Into a small bowl mix together: butter, garlic and basil. Season with salt and pepper. Set aside.
Brush bread slices with herb butter.
To create two sandwiches, onto 2 slices of bread add the following to each: 3 slices prosciutto, 6 leaves spinach, 3 oven roasted tomatoes, 1-2 pepperoncini, and ⅓ cup cheese. Top with bread slices.
Heat a large non-stick skillet over medium-high heat. Add sandwiches and cook for approximately 3 minutes or until golden crust forms. Carefully flip sandwiches and continue cooking until golden.
Allow sandwiches to rest momentarily prior to cutting.
