Preheat your grill or grill pan over medium-high heat.
In a small bowl, combine the fresh mixed herbs, garlic powder, salt, pepper, and olive oil. Rub this mixture evenly over the chicken breast.
Grill the chicken breast for about 5-6 minutes per side until fully cooked and juicy. Allow it to rest for a few minutes before slicing.
While the chicken grills, drain and pat dry the canned chickpeas. Toss them with a pinch of garlic powder, fresh herbs, salt, and a tiny drizzle of olive oil.
Spread the chickpeas on a baking sheet and roast in a preheated 400°F oven for about 15 minutes or until they turn crispy, stirring halfway.
Prepare the light Caesar dressing by whisking together the nonfat Greek yogurt, lemon juice, Parmesan cheese, and a pinch of salt and pepper.
In a large bowl, toss the romaine lettuce with the dressing until the leaves are well coated.
Arrange the dressed lettuce on a plate, top with sliced grilled chicken, and sprinkle the crispy chickpea croutons over the top.
Finish with a light garnish of extra herbs and a squeeze of lemon if desired, then serve immediately.
