Marinated Watermelon & Tomato Salad

• 10 cups cubed seedless watermelon (from a 5-pound baby watermelon)
• ¼ cup fresh lime juice
• 1 ½ pounds chopped tomatoes
• ½ sliced small red onion
• ½ cup torn fresh basil leaves
• 2 tablespoons olive oil
• ¾ teaspoon salt
• ¼ teaspoon pepper

Combine watermelon and lime juice in a large bowl. Let sit, stirring occasionally, at room temperature for 15 minutes. (The watermelon will absorb the lime juice as it sits.)

Add remaining ingredients; toss to combine.
