Salsa fresca redux

Back by popular demand is the salsa fresca recipe from The Perfect Pantry that I first tried and posted last year. This time I changed it slightly from the original by adding a little bit of kiwi (because I had it on hand) and a little crushed mint leaves (from my garden). This is the original recipe and it's perfect just the way it is. And it's quite beautiful, a great side for grilled chicken.

Watermelon, mango, and tomato salsa fresca

1 cup watermelon, diced
1 mango, diced
1/2 cup ripe tomato, seeded and diced

1/2 cup seedless (English) cucumber, diced
1 jalapeño pepper, seeds and ribs removed, minced
Juice of 1/2 lime (or more to taste)
Kosher salt to taste (about 1/4 teaspoon)

Combine all ingredients in a mixing bowl. Chill until ready to use.
