Tossed this in a pan the other day so that I could heat something quickly and not heat up the apartment too much, and it's so good! I have been eating it cold and hot for three days and it's still really yummy.
1 can of whole new potatoes, cut in chunks
1 can of diced tomatoes, not drained
1 onion, chopped
1 cup (or you can use a whole can if you want) cooked or canned garbanzos
1 tbsp Madras curry powder (or any favorite spices -- I bet this would also be good with Mexican or Italian spicing)
Throw everything in a saucepan, bring to a boil, reduce heat to medium, and boil until the sauce gets thick, about 20 minutes. Since it's all fully cooked, you could also drain the tomatoes and just heat it until everything's hot, but I like the way the flavors blended.
