This is a more basic take on a Mediterranean bowl - minimizing ingredients to keep it simple for grocery shopping, while still giving you a nice balance of nutrients to carry you through the afternoon. This meal is very meal-preppable - just heat back up the things you want hot (the chicken, rice, and sweet potatoes), and add the other cold things (the tzatziki, veggies, and feta) to finish it off! The two components that need roasting (sweet potato and chicken) are cooked at the same temperature, so if you play your timing right, you can make this super efficient to make the most of your meal prep time.
