4 heaping cups cubed seedless watermelon
1 cucumber diced, reserve half
2 medium tomatoes diced, reserve half
1 small onion diced, reserve half
1 small box peppers diced, reserve half
2 garlic cloves
1 small bunch basil
4 T apple cider vinegar or wine vinegar
1.5 t salt, or to taste
1/2 t black pepper
Set aside the reserved half of the chopped cucumber, tomatoes, red pepper and green onions and place the remaining half in a blender. Add the watermelon, garlic, basil, vinegar, salt, and pepper. Blend until smooth. Taste and adjust seasonings. Stir in reserved seasonings, and chill for 3-4 hours or overnight.
Note: I have eaten it immediately without chilling, and it was still delicious
