Make the dressing: Mix the dressing ingredients in a medium-bowl. Add the olive oil, dijon, red wine vinegar, garlic, sugar/honey, italian seasoning, salt and pepper.
Next, shred the brussel-sprouts using a food-processor fitted with the slicing attachment and pulse till the brussels sprouts are thinly sliced. You can also use a sharp knife to slice the brussels sprouts if you don't own a food processor.
In a large bowl, add the shredded brussels and pour the dressing all over. Use a fork to coat the brussels in the dressing. Allow the dressing to sit for 30 minutes before you let the brussels marinate in the dressing. You can prepare all the other ingredients while the brussels soak up the dressing.
Next, add the chickpeas and salami, tomatoes olives, pepperoncinis red onion, provolone cheese cubes and shaved Parmesan. Mix well. Add extra black pepper to taste. Serve!
