Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Pat the chicken breast dry with a paper towel. Rub with 1 teaspoon of avocado oil and season with half of the sea salt, black pepper, and garlic powder.
Rinse and thoroughly dry the chickpeas. Toss them with the remaining 1 teaspoon of avocado oil and the remaining sea salt.
Place the chicken and chickpeas on the prepared baking sheet. Roast for 20-25 minutes until the chicken reaches an internal temperature of 165°F and the chickpeas are golden and crisp.
While roasting, prepare the dressing by whisking together the Greek yogurt, lemon juice, Dijon mustard, anchovy paste, and one finely minced garlic clove in a small bowl.
Wash and chop the romaine lettuce into bite-sized pieces and place them in a large mixing bowl.
Once the chicken is cooked, let it rest for 5 minutes before slicing it into thin strips.
Toss the romaine lettuce with the prepared Caesar dressing until evenly coated.
Plate the dressed greens and top with the sliced roasted chicken, crispy chickpeas, and a sprinkle of parmesan cheese.
