Prepare the Sauce: In a small bowl, whisk together soy sauce, maple syrup, rice vinegar, sesame oil, sesame seeds, garlic, and ginger. Set aside.
Cook Chickpeas: Heat olive oil in a large skillet over medium heat. Add the chickpeas and cook for 5 minutes, stirring occasionally until they start to crisp.
Add Sauce & Thicken: Pour the sauce over the chickpeas and stir to coat evenly. In a separate bowl, mix the cornstarch with water to form a slurry. Pour the slurry into the skillet and cook for an additional 2-3 minutes until the sauce thickens and becomes sticky.
Serve: Serve the sticky sesame chickpeas over cooked rice or quinoa. Garnish with sliced green onions and extra sesame seeds if desired. Enjoy!
