Gather the recipe ingredients. Prep each, starting with the watermelon: wash first, peel the outer skin, and cut into cubes. Place in a large measuring cup. Roughly mince the garlic.
Dice the red pepper, cube the cucumber, and chop the tomato, basil, and mint. Place ingredients in separate bowls.
For the topping: reserve approximately 1 tablespoon each (chopped a little finer): watermelon, red pepper, and tomato. Blend these together in a bowl with diced jalapeño, cubed avocado, diced green onions, and ½ teaspoon of chopped basil and mint.
Place the watermelon cubes, peppers, tomato, and shallots in a food processor and pulse a few times.
Add cucumber, garlic, salt & pepper, basil, mint and jalapeño.
Pulse until blended but still chunky. Squeeze in ½ lime and pulse once to blend.
Pour into a large measuring cup. Stir in olive oil & apple cider vinegar. Adjust salt & pepper to taste. Refrigerate until chilled for 1 hour or more.
Serve in separate bowls and each served with toppings added. Enjoy!
