1. Preheat oven to 450F (232C). Set oven rack in center of the oven. Line a sheet pan with parchment paper.
2. Cut the top end (not the root) off of the garlic head, exposing the tops of each garlic clove. Drizzle 1 tsp of olive oil over the cloves and wrap loosely in foil. Set it on the parchment lined pan. Slice the bell peppers in half, deseed and lay flat, flesh side down, on the parchment lined sheet pan. It’s okay to press on them a bit. Set the timer for 20 minutes and roast the peppers and garlic.
3. While the peppers and garlic are roasting, trim the stem of the eggplant. Slice the eggplant lengthwise into at least 6, ¼” (2½cm) pieces. Sprinkle each side with a pinch of sea salt and place in a colander to drain for 15 minutes. Rinse and pat dry. Spread each side with a about ¼ tsp olive oil. Place on the same sheet pan as the peppers are roasting on and roast for 20 minutes. The peppers, garlic and eggplant should come out of the oven at the same time. (Peppers and Garlic roasts for 40 min., Eggplant roasts for 20 minutes)
4. Place peppers in a lidded container for 20 minutes. This will make the skin release with ease. Peel pepper skin and set peppers aside. Peel the garlic then mash the cloves until a paste forms. Set aside.
5. Mix the tapenade with red wine vinegar, set aside.

To Assemble:

1. Slice the bread lengthwise with a serrated knife. Dig out the inside of the bread on both sides. Try to leave enough crust as to keep the sandwich sturdy. Save the bread dug out and make croutons or bread crumbs with it. Optional – brush on a bit of olive oil, no more than 1 Tbs., on the insides of the bread. Be careful here, the bread can get soggy.. so only this if you love a bit more olive oil (I brush it on mine).
2. Spread the garlic on both sides of the bread. It will be thin. Spread the tapenade on both sides of the bread. Yes, all of it. Press as you spread.
3. On the bottom side of bread, layer in the following order: 3 slices of eggplant, artichoke, bell pepper, 3 slices of eggplant, a pinch of salt and a few grinds of pepper, pepperoncini, chard or spinach and optional cheese. Place top on sandwich and gently press down.
4. Tightly wrap the sandwich three times to ensure nothing leaks out and place it in the fridge. Place a heavy object on top of the sandwich, such as cast iron skillet, or box of wine. Let marinate and press for at least 3 hours. Overnight is better.
5. Cut into 2″ wide pieces and then cut in ½ for a smaller sandwich. I yield 5, 2″ wide (5cm) pieces, but cut the center cuts in half to make smaller sandwiches. Cut to your needs.
6. Rewrap any remaining pieces tightly in plastic wrap and store for up to two days.
