1. Season the chicken breast evenly with 0.125 tsp sea salt, 0.125 tsp black pepper, and the garlic powder.
2. Heat the olive oil in a skillet over medium-high heat and cook the chicken for 6-7 minutes per side until golden and the internal temperature reaches 165°F.
3. Remove the chicken to a cutting board to rest; add the drained chickpeas to the same skillet and sauté for 4-5 minutes until they are slightly crisp and toasted.
4. In a small mixing bowl, whisk together the Greek yogurt, lemon juice, Dijon mustard, nutritional yeast, and the remaining salt and pepper until the dressing is smooth.
5. Roughly chop the romaine lettuce and place it into a large serving bowl, then slice the rested chicken into thin strips.
6. Drizzle the creamy dressing over the lettuce and toss to coat, then top with the sliced chicken, toasted chickpeas, and grated parmesan cheese.
