In a large bowl, add the cucumber, melon, herbs, cheese, onion (if using), lemon, and salt and toss to coat (I like to just use my hands to toss this salad).
Add avocado and gently toss again (I like to add the avo after tossing the other ingredients since it can get bashed up easily - it’s mostly just a presentation thing!).
Serve in the mixing bowl or transfer to a shallow salad bowl or large serving platter. Drizzle generously with your best olive oil and top with black pepper and a sprinkle of kosher or flaky salt to finish.
Notes
Substitutions:
To make vegan, skip the mozzarella and just add another avocado.
Use any type of melon or other seasonal fruit.
Storage:
Store leftovers in an airtight container in the fridge for up to 3 days
Leftovers + Repurposing:
Enjoy this salad right out of the fridge or let it sit out for 30 minutes for optimal flavor.
Top with a squeeze of lemon and sprinkle of salt to wake it up.
