Let's start by mixing together the dressing. In a bowl add in the dijon mustard, black pepper, salt, red wine vinegar, and then slowly stream in the olive oil while whisking. Taste and adjust seasoning if needed. Set aside.
Next up if you are making your own croutons, dice up some bread and toss into an oiled pan and place over medium high heat. Toast the bread until brown on all sides. Set aside.
Into a bowl add the romaine, arugula, tomatoes, onions, cucumbers, pickles, parmesan, salami, and croutons. Drizzle over dressing and toss. Enjoy!
