This was really delicious and versatile. You could use feta instead of mozzarella, or better yet, burrata. You could use a different kind of melon, or even ripe papaya and mango would be good here. I used mint instead of basil because I like it so much better. I also used green onions instead of red, since that’s what I had on hand. I think it would be better with red onions, but the green onions were still pretty good.
And yes, serve with crusty bread and it can be a light meal.
Also, unsurprisingly doesn’t keep very well. Definitely eat within 24 hours. Might hold up a little better with red onion and feta, but the mint will still wilt.
