Preheat your oven to 450 degrees.
Tzatziki: Grate cucumber and transfer to a fine mesh strainer. Using several paper towels, squeeze all the extra water out of the cucumber. Combine shredded cucumber to a medium bowl with the greek yogurt. Add garlic powder, salt, extra virgin olive oil, white vinegar, and dill. Stir, and cover in the fridge until ready to use.
Seasoning: combine salt, Italian seasoning, garlic powder, corn starch, black pepper, onion powder, paprika, ground cinnamon, and ground nutmeg.
Farro: Cook your farro or other whole grain according to package directions while baking your chicken.
Bake Chicken: Line baking sheet with aluminum foil or parchment paper and spray with non-stick cooking oil. Place 4 chicken breast portions on the baking sheet and coat evenly with the greek seasoning. Spray again with non-stick cooking spray and bake for 15-20 minutes, or until cooked through.
Greek salad: dice the other half of the cucumber, quarter the cherry tomatoes, dice your red onion, and chop the olives. Mix all the ingredients together in a large bowl. Season the salad with salt, some freshly cracked black pepper, olive oil, red wine vinegar, and the juice of one lemon. Stir.
Portion everything evenly among 4 food containers, (or plates if you want to eat it now!)
