There are a lot of recipes online for watermelon and feta salad. I found one from Giada De Laurentiis, another one from the Barefoot Contessa, Ina Garten, and yet another from Paula Deen. Of course, my online friend from Toronto, Peter, has a great recipe as well.
I combined watermelon, feta cheese, red onion and mint leaves from my garden with a dressing of lemon juice and honey. It’s simple and delicious. Try it. You’ll be surprised how really good these combination of flavors are. Let me know if you do make this salad and how it turns out. I like feedback! 
Hello Kitoula, I really love this salad! I like the way you’ve cut the watermelon.

Thank you Eri. I used a melon baller. They’re not perfect but I like the way they look too.
