This refreshing salad gets a tangy bite from olives and red onion.
Cut watermelon flesh into 1 1/2-inch chunks; remove seeds. Toss watermelon with onion, olives, and cilantro to combine.
Drizzle olive oil and vinegar over salad and sprinkle with salt and pepper. Toss and adjust seasonings with more oil, vinegar, salt, or pepper as desired. Serve immediately.
