Pumpkin Leaves with Peanut Sauce

So I really like this recipe and if you can get this at home try it out..it's a recipe here in TZ..but I think it applies to alot of countries in South/East Africa as they eat something similar. Usually you are supposed to grind peanuts but I just dissolve one tablespoon of chunky peanut butter in a cup of hot water (preferably the water you boil the pumpkin leaves in) since I don't have a blender. You need about 5 stalks of pumpkin leaves, 1 tomato, 1/2 an onion, and 1 Tbsp of peanut butter. Remove veins from pumpkin leaves and chop off any tough parts to the stem. Then cut the leaves in ribbons and finely chop the stems. Cover and boil it in water with salt for 5 mins. Drain the leaves. Reserve 1 cup of the liquid and mix with 1 Tbsp of peanut butter. Chop onions. Peel the tomato and chop. In a seperate pan fry the onions in oil when brown, add the tomatoes. When it begins to look like a sauce (tomatoes cook down), add the peanut liquid. Add salt to taste. Boil for a minute and add the pumpkin leaves. Boil until liquid is reduced. Serve with rice..yum!
