Season the chicken breast with half of the sea salt and black pepper.
Heat a skillet over medium heat and cook the chicken breast for 6-7 minutes per side until the internal temperature reaches 165°F.
In the same skillet, cook the bacon slice until it is crisp, then remove and chop into small bits.
In a small bowl, whisk together the Greek yogurt, olive oil, Dijon mustard, lemon juice, minced garlic, and the remaining salt and pepper to create the dressing.

Slice the cooked chicken breast into thin strips.
In a large mixing bowl, toss the romaine, tomatoes, and cucumber with the prepared Caesar dressing until evenly coated.
Transfer the salad to a serving bowl and top with the sliced chicken, bacon bits, and roasted chickpeas.
