Mix together the calabrian chile and tomato pesto and set aside. Lightly toast the schiaccata.
Quickly sear the folded slices of mortadella just to get color on each side. Toss the arugula with the olive oil, lemon juice, salt and pepper.
Build the sandwich: spread both sides with the tomato chile mixture. Layer the mortadella on the bottom, top with torn burrata ball, then with the seasoned arugula.
