A super fast, easy, and refreshing salad perfect for warm weather. Combines sweet watermelon, cool cucumber, tangy feta (optional), fresh mint, and a light lime and olive oil dressing. Ideal for BBQs, potlucks, or a simple snack.
Best enjoyed fresh. Store leftovers in an airtight container in the refrigerator for about 1-2 days; texture may become watery as watermelon releases liquid. Slice red onion very thin. Chill ingredients beforehand for immediate serving. Cut watermelon and cucumber into similar-sized pieces. Don't dress more than 30 minutes ahead of serving.
