Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse the chickpeas and pat them extremely dry with a paper towel to ensure maximum crispness.
Toss the chickpeas with half of the olive oil, garlic powder, and a pinch of salt and pepper; roast for 20 minutes until golden and crunchy.
Season the chicken breast with the remaining salt and pepper, then grill or pan-sear over medium heat for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the tough stems from the kale and chop the leaves into thin ribbons, placing them into a large mixing bowl.
In a small jar, whisk together the remaining olive oil, tahini, lemon juice, and nutritional yeast until smooth.
Pour the dressing over the kale and massage the leaves firmly with your hands for 2 minutes until they become tender and dark green.
Slice the grilled chicken into strips and top the massaged kale with the chicken and warm roasted chickpeas.
