Start by cutting your watermelon in half and scooping out the flesh with a melon baller or knife. Cut it into bite-sized cubes—aim for about 3/4-inch pieces. You'll want roughly 4 cups total, which is easier than it sounds. Pro tip: chill your watermelon for at least an hour beforehand if you can, because cold fruit makes this salad feel extra refreshing.
Grab a shallow bowl or cutting board and slice your cucumber into thin rounds. You don't need to peel it unless you really want to—the skin adds nice color and texture. Aim for about 1/2 cup total sliced pieces. Set it aside while you prep the rest.
Toast your pumpkin seeds in a dry skillet over medium heat for 3-4 minutes, shaking the pan occasionally so they don't burn. You'll hear them start popping when they're ready—that's your signal to pull them off the heat. Let them cool for a minute, then measure out 1/4 cup. Toasted seeds make a huge difference compared to raw ones.
Chop your fresh mint leaves into small pieces—don't go too fine or they'll turn to mush. I personally aim for rough 1/4-inch pieces that you can still see and taste. Measure out 1/4 cup and set aside. This is also where you can prep everything ahead if you're making this for a party.
In a small bowl or glass, whisk together your lime juice, olive oil, and honey until the honey dissolves completely. Add a pinch of salt and 1/4 teaspoon black pepper, then taste it. The dressing should taste slightly sweet and tangy—adjust the lime juice if it's too heavy or the honey if it's too tart.
Put your cubed watermelon in a large serving bowl, then layer in the cucumber slices, pomegranate seeds, crumbled feta, and toasted pumpkin seeds. Don't toss it yet—this makes your watermelon feta salad recipe look gorgeous when you serve it. I always do this step for photos because the colors are seriously Instagram-worthy.
Pour your dressing right over everything and toss gently but thoroughly, making sure the dressing coats every component. Add the chopped mint last and give it one final toss. Taste and adjust salt if needed. Serve immediately, or let it chill for up to 30 minutes before serving.
