Mix freshly-squeeze orange juice, tomato paste, apple cider vinegar, arrowroot starch, tamari, chili flakes, and ginger in a bowl.
Heat a pan over medium heat. Pour the sauce in. Let it thicken and bubble, stirring occasionally for 5-6 minutes.
Add chickpeas. Increase heat to medium-high until it starts to simmer. Reduce heat to medium-low, cover, and cook for 10 minutes.
When you've taken it off the heat, stir in sesame seeds.
