Note: I ended up using half as much meat and cheese because the original recipe made the sub a little too big and hard to manage. If you want the full-on, super meaty experience, double the meat and cheese in this recipe.

In a large bowl, whisk together olive oil, red wine vinegar, balsamic vinegar, parsley, shallot, oregano, and red pepper flakes. Season heavily with salt and pepper.
Add in red onion, tomatoes, and fennel. Toss to thoroughly coat vegetables in vinaigrette. Let vegetables rest in vinaigrette for 20 minutes, tossing again halfway through. Strain vegetables into a bowl and reserve remaining vinaigrette.
Open up bread and layer on mortadella, salami, provolone, and hot capicola. Top with marinated vegetables, pepperoncinis, red peppers, and lettuce.
Light one chimney full of charcoal. When all the charcoal is lit and covered with gray ash, pour out and spread the coals evenly over entire surface of coal grate. Set cooking grate in place, cover grill and allow to preheat for 5 minutes. Clean and oil the grilling grate. Place bricks on grill, cover grill and let fire cool down to medium-low, between 300-325°F. Transfer sub to grill and place a large sheet pan on top of sandwich. Wearing well insulated grilling gloves, carefully balance bricks on sheet pan. Cover grill and cook until cheese has started to melt and sandwich has flattened, about 15 minutes. Remove sandwich from grill, slice into 4-6 portions and serve with reserved vinaigrette.
