This salad is chockful of veggies and heart-healthy fats from the olives and olive oil. It offers a significant source of lycopene from the tomatoes, vitamin K from the cucumbers, plus a slew of antioxidants. If you wish to add protein to make it more satiating, I suggest adding a can of drained tuna or shredded rotisserie chicken. If making plant-based, stir in one can of chickpeas or a handful of shelled edamame.
