Add ¼ cup of water to the pan and heat on medium-high. Add onions and saute for 2-3 minutes.
Add minced garlic and jalapeno. Saute for an additional 2-3 minutes. Add water as necessary.
Add dry spices. Saute momentarily.
Add sweet potatoes. Mix to coat potatoes in spices. Add 2 cups of water. Cover and simmer for 15-20 minutes or until potatoes are soft and breaking slightly (do not overcook). Add chickpeas and simmer for 2-3 minutes.
You can add more water in small amounts if necessary. As the potatoes break down slightly the sauce will thicken.
Allow to sit and thicken slightly before eating.
