Season the chicken with all the chicken spices EXCEPT avocado oil. Mix well.
Heat a cast iron skillet on medium heat. Cooking in batches, add about 2 tbsp of avocado oil and cook the chicken for about 4-5 minutes per side.
While the chicken is cooking, make the cucumber sauce by mixing all the ingredients in a bowl.
To plate, add a scoop of the cucumber yogurt sauce, top with a handful of arugula, a squeeze of lemon juice on top of the arugula, and the chicken. Then top it with the mango chutney.
Serve immediately and enjoy.
