Marinate the bell peppers with garlic and basil. Drizzle with 1 tablespoon of olive oil and ½ tablespoon of balsamic vinegar, and salt and pepper to taste.
Place the bread in the oven at 350F for 6 to 8 minutes to make the outside toasted and crunchy. Take it out of the oven and cut it in half lengthwise.
First spread the arrabbiata pesto sauce, then layer the arugula and red onion slices. Season with salt and pepper, a drizzle of olive oil, and a drizzle of balsamic.
Add the bell peppers, then the salame, pecorino cheese, and lastly lay the mortadella to act like a blanket to wrap everything together.
That’s it! Simple as that. One of the most delicious meals you can make in less than 15 minutes.
