Prepare all fresh ingredients by washing, peeling, and dicing the watermelon into small cubes, finely chopping the red bell pepper and red onion, and chopping the cilantro leaves. Arrange each ingredient on your cutting board for easy access.
Watermelon cubes
Combine the diced watermelon, chopped bell pepper, red onion, and cilantro in a large mixing bowl. Use a spoon or spatula to gently toss all the ingredients together, ensuring an even distribution of flavors and textures.

Measure and pour in the lime juice over the mixture, then sprinkle with salt and black pepper. Stir gently again to incorporate the seasonings evenly. You should see the lime juice coating all the ingredients and the salt dissolving into the mixture.

Let the salsa sit at room temperature for 5 minutes to allow the flavors to meld. During this time, the watermelon releases some juice, and the herbs release aroma, creating a vibrant mixture. Visual cues include the mixture appearing juicy and slightly translucent from the lime juice.
Taste and adjust seasonings if necessary, adding more salt or lime juice as desired. The finished salsa should be colorful, juicy, and crunchy, with a balance of sweetness, tang, and spice.
Serve immediately as a topping for grilled dishes, scoop onto tortilla chips, or enjoy plain as a refreshing snack. Garnish with additional cilantro if desired for presentation.
