Boil the chickpea pasta in salted water until al dente, then drain and rinse with cold water to stop the cooking process.
Season the chicken breast with sea salt and black pepper, then grill or pan-sear over medium heat until fully cooked through.
Allow the chicken to rest for a few minutes before slicing it into bite-sized strips.
In a small mixing bowl, whisk together the Greek yogurt, Dijon mustard, lemon juice, olive oil, and minced garlic until smooth.
In a large bowl, combine the cooled pasta, sliced chicken, chopped romaine lettuce, and halved cherry tomatoes.
Pour the yogurt dressing over the salad and toss gently to ensure every ingredient is evenly coated.
Top with the shredded parmesan cheese and serve immediately while the greens are crisp.
