Heat the water in a skillet over medium-high heat. Add the onion, zucchini or bell pepper, chili powder, cumin, paprika, garlic powder, oregano, allspice, pepper flakes, and salt. Cook, stirring occasionally, for 6 to 8 minutes, until the onion has softened. If the mixture is drying out and sticking, add another splash of water. Add the mashed chickpeas, lime juice, and molasses and stir thoroughly. Reduce the heat to medium and cook, stirring, for 8 to 10 minutes, until mixture is heated through. Taste, and if you’d like extra salt or heat, add additional seasonings. If mixture is still dry or sticking, add another 2 to 3 teaspoons of water, increase the heat briefly, and scrape the skillet to help bring up the spices from the bottom of the skillet.
