Preheat oven to 400 degrees. Add the chickpeas to a baking dish (9” x 9” or similar size). In a blender, add cliantro, lime juice or vinegar, mango, pumpkin seeds, maple syrup (if using), garlic, salt, and water. Cover dish with aluminum foil. Bake at 400 for 20 minutes. Remove foil, stir through, and bake another 5-8 minutes (see note), until sauce has thickened. Once cooked as desired, remove from oven and serve (see serving suggestions). Serves 4-5, depending on accompaniments.
