In a small bowl, combine coconut sugar, apple cider vinegar, ketchup, soy sauce, and garlic. Stir together. In another small bowl, whisk together cornstarch and water. Pour cornstarch slurry into sauce bowl and whisk together. Set aside.
Add oil to a skillet over medium heat. Once hot, add bell peppers and onions and cook until softened (about 3-4 minutes). Then add in chick peas and stir to combine.
Add in the sauce and stir to cover all of the chickpeas and vegetables. Stirring often, let cook until sauce has begun to thicken and bubbling.
Remove from heat. Serve immediately with any sides and garnishes desired.
