For the Zambian Meal, along with the Zambian Chapati that I made, I had to pair it with a lentil or a dal, as we normally do. The search took me to this recipe of Beans with Tomatoes, Onions, and Green Bell Pepper Recipe from celtnet org which is basically of Zambian Origin. It's a classic vegetarian stew and is No oil Dish.
I used Black-eyed peas, which is quite common in my house, and was happy to use it as the taste is something familiar. However, when I read it further I realized there was no oil used. Amma was so surprised when I told her that this dal or stew was made without oil. She said it tasted great and said we could easily include this in our regular meal. Of course, the stew was quite bland for our taste buds, however, the peri peri took care of it.
