Step 1

Make the piquillo-jalapeño mayonnaise: In a small bowl, stir together all ingredients and set aside.

Step 2

Make the sandwich: In a medium skillet over medium-high heat, heat the oil. Add the two focaccia halves, cut-side down, and fry until golden brown and crisp, 3 to 5 minutes.

Step 3

Spread the piquillo-jalapeño mayonnaise evenly onto the toasted slices. Layer one slice with the mortadella, pecorino, basil and parsley, and cover with the top half of bread. Serve.
