Drain and rinse the chickpeas thoroughly. Set aside.
Mince the garlic and sauté with 1 tablespoon of oil over medium heat until fragrant and golden, about 1–2 minutes.
In a small bowl, whisk together the arrowroot powder and 2 tablespoons of vegetable broth. Set aside.
Add the sesame oil, tamari, maple syrup, rice vinegar, ginger, and remaining vegetable broth to the pan. Whisk to combine.
Re-whisk the arrowroot slurry to prevent clumping, then pour into the pan. Stir well.
Cook the sauce over medium-low heat until it begins to bubble.
Add the chickpeas and stir gently to coat. Cook for 5 minutes until the sauce thickens and chickpeas absorb the flavors.
Turn off the heat and let the dish sit for 5 minutes to allow the flavors to meld.
Serve over rice, quinoa, or with steamed vegetables. Top with toasted sesame seeds and green onions if desired.
