Start by making a pesto. In a food processor, pulse mint, basil, pine nuts, garlic, and olive oil until a coarse paste forms. Add more olive oil if needed.
Stir in pecorino cheese and season to taste with salt and pepper. Set aside.
Lightly toast your bread of choice.
Next, season your zucchini. For one sandwich, thinly slice a whole small zucchini lengthwise.
Add the zest of a whole lemon, a small drizzle of lemon juice, and olive oil. Season lightly with salt and pepper.
To assemble, spread a layer of pesto on the bottom half of the toasted bread. Top with arugula. Layer on the seasoned zucchini. Top with burrata and spread out evenly.
Season the burrata lightly with salt and pepper. Drizzle with olive oil.
Top with the second half of the bread, cut in half and enjoy!
