Notes

  • For more staying power, bulk up the salad with a can of drained, rinsed chickpeas. The extra protein and fiber can turn the dish into a satisfying vegetarian entrée.
  • This Mediterranean-inspired dish is delicious with some crumbled feta cheese, diced fresh mozzarella, or miniature mozzarella balls to the dish for a creamy addition.
  • Stir in 1 pitted, diced avocado. The fruit will add a nice, creamy texture and richness. If you're not serving the salad within 30 minutes, wait to add the avocado until the last minute. The avocado will turn brown if it sits out for too long.
  • Instead of making your own vinaigrette, you can substitute with about ½ cup of your favorite store-bought Italian dressing.
