This is my new Italian Sub! An Italian Sub is one of my favorite sandwiches to make because you can have so much fun with all the toppings. It’s the perfect lunch or quick and easy dinner!


1 small baguette


Dijon mustard

4 ounces provolone cheese

2 ounces mortadella

2 ounces pepperoni

1 ½ ounces Calabrian salami

3 to 4 peppadew peppers, thinly sliced

1  to 2 tablespoons finely chopped giardiniera, optional

Marinated Red Onions

Italian Seasoning Blend, optional

¼ cup thinly sliced iceberg

1 to 2 dill pickle slices


Preheat oven to 400°F.


Slice the baguette almost in half, leaving it connected on one side. Make it ‘skinny’ by removing the bread filling on the inside. Place the bread on a baking sheet. Spread mayonnaise evenly on both sides of the bread. Add Dijon mustard one side of the bread. Layer the provolone cheese, mortadella, pepperoni, Calabrian salami, peppadew peppers, giardiniera, and marinated red onions and a drizzle of the red onion oil inside the sandwich. Top off with a sprinkle of Italian seasoning blend.


Bake in the oven, open-face, for 5 to 8 minutes or until the bread is toasted and the cheese melts.

Remove from the oven, add the iceberg lettuce and pickle slices. Slice in half and enjoy!
