- Make the spice mix. Include powdered ginger, if using. Set aside. (This step can be done the night before in order to make dinner prep even quicker.) 
- Chop the onions and set aside. Grate the garlic and ginger and set aside in a separate bowl. 
- Melt the butter in a heavy-bottomed pot over medium high until bubbling. 
- Add the onions and sauté until soft, 3-4 minutes. Add the garlic and ginger and sauté until fragrant, another 30-60 seconds. Add the spice mix and sauté again until fragrant, 30-60 seconds. 
- Pour in the tomatoes and coconut milk and bring to a simmer. Add in the garbanzo beans and return to a simmer. This may be served immediately or left to simmer for up to 1 hour, stirring frequently. 
- About 5 minutes before serving, stir in the chopped greens and cook until slightly wilted. Serve immediately or refrigerate for up to 3 days. 
- Serve over rice, diced potatoes, or with flatbread.
