Ingredients
Method
- Slice open the ciabatta bread in half. Drizzle with olive oil and toast it on medium-high heat using either a panini press for a few minutes till it becomes lightly golden brown for a crispy sandwich. I like using the panini grill because you can get those beautiful grill marks. You can also use a cast iron skillet.

- Spread a generous amount of pesto on both slices of bread.

- Start with the bottom half of the ciabatta bread start to layer the sandwich with mozzarella cheese, prosciutto, slices of heirloom tomatoes, and arugula, then drizzle the balsamic vinegar glaze, close the sandwich with the top half of the bread, and serve! Enjoy right away, or wrap in parchment paper and store it in an airtight container in the fridge until it’s ready to serve.

Notes
SUBSTITUTIONS
- You can use sourdough bread instead of ciabatta.
- Use any ripe tomato slices if you can’t find heirloom tomatoes.
- Do not substitute the balsamic glaze for balsamic vinegar, that is not the same thing and it will make a huge difference in the sandwich!
- Instead of sliced creamy mozzarella, some great options are mozzarella balls or burrata cheese.
