If you love Mediterranean flavors as much as I do, then try this recipe! Just don't skip the fennel. This ingredient adds balance to the other flavors and brings everything together. These nightshade-free chicken tacos are delicious served with any type of tortilla or flatbread. If you are on a low-carb or keto diet, serve the chicken and toppings over a bed of lettuce or steamed dark leafy greens.
