Tzatziki will be more flavorful if made ahead of time. If you avoid dairy, I have found that plain, unsweetened coconut milk or cashew milk yogurts taste best. If you avoid nightshades, skip the cayenne, cumin, and paprika; double the cinnamon portion and add more fresh herbs (i.e. more mint, oregano, or dill). This recipe is gluten free. I recommend pairing this with a side salad to obtain your optimal vegetable intake for this meal. Enjoy!
