Mediterranean Quinoa Bowls with Cashew Tzatziki Sauce comes together with mixed greens, quinoa, cucumber, tomato, red onion, green onion, and olives. This Mediterranean quinoa bowl might be my favorite to date because of all it has going on. From the greens base and the fluffy quinoa to the soft pita bread and crunchy veggies, this lunch has it going on. You can't forget about the mouth-watering sauce either, though! That might be the star of this show.
