Finely chop and combine all ingredients in a large bowl.
Add lime juice and seasonings and toss well. Chill for 15 minutes and it is ready to serve.
Notes
Using fresh ingredients is the key here, so make sure you use the best produce you can, preferably organic. If you’re planning to make this watermelon salsa for a potluck or a BBQ party, I would recommend assembling everything right when you want to serve it.Depending on what I have at hand, I also like to add other veggies to the salsa. Cucumbers, tomatoes, white onions, celery, pineapple, and cabbage are all great choices. You can also add avocado if you want to.
