1. Preheat oven to 500 degrees.

To Prepare the Aioli

1. Line a medium pan with foil and place both whole peppers with stems attached onto the pan.
2. Cut the top and bottom off a head of garlic and place in a small pocket made from a piece of foil. Drizzle one tablespoon of oil and one tablespoon of water over garlic and pinch the foil pocket closed. Place this foil packet on the pan with the peppers. Roast for ten minutes and turn peppers one third, roast for ten more minutes and turn another third then roast for ten more minutes and remove from the oven. (If the skin isn’t charred all around, roast for another five minutes until nicely blackened and charred.)
3. Raise the oven temperature to 550 degrees.
4. Immediately place whole red peppers into a large zipper seal bag and seal to steam the skins off. Allow the peppers remain in the plastic bag for ten minutes, then take them out of the bag and place them on a cutting board. Peel the skin off and discard. Then split the peppers down the middle, remove stems and seeds and place the roasted flesh of the peppers into a blender (the peppers collect moisture inside while roasting, try not to add this excess liquid to the blender). Remove the roasted garlic head from the foil pouch and squeeze out the roasted cloves into the blender, adding them to the peppers (you may want to use a tiny piece of foil to squeeze the garlic out of the skin so you don’t burn your fingers).
5. Add the mayonnaise to the blender and set to puree. Lift off the cap and slowly drizzle in 3 tablespoons of olive oil with motor running until mixture is thick and creamy.

To Prepare the Sandwich

1. Take the top crust off the 12 inch loaf by running a bread knife just below the top. Next split the loaf horizontally in half so you have two open halves. Spread two tablespoons of the aioli on each inside cut.
2. Then begin layering the cold cuts on the bottom half and finish with the provolone. Top with half of the basil leaves and place the top half of the bread over the basil pressing the aioli side down over the basil.
3. Heat the panini grill to hot or heat a grill pan on the stove. Brush one tablespoon of olive oil on the top half of the sandwich and brush the other tablespoon of olive oil on the panini press or grill. Place sandwich on heat over brushed oil and brown both sides, pressing down slightly to flatten sandwich. Heat until the bread is nicely browned.
4. Line a small sheet pan with foil and place the grilled sandwich onto the foil.
5. Lay the other half of the basil leaves and all of the sliced tomatoes over the top of the browned top of the sandwich.
6. Mix the Parmesan, mozzarella, Muenster and oregano in a small bowl and spread over the basil and tomatoes (Try to get the cheese to stay in place by pressing down with your hands).
7. Place the pan in the hot oven for 5-7 minutes to melt and brown cheese. To brown further, place under a broiler for a few minutes.
8. Serve by cutting into four even pieces. Great served with the roasted red pepper aioli on the side as a dipping sauce.
