This receipe is from The African Cookbook by Bea Sandler, p. 182 (in the appendices). It's an old cookbook, which I purchased at the Smithsonian some years ago; it's one of those intended for American audiences, and provides various substitutions for ingredients, menus for a common meal in various countries, and the like.
(The Africa Cookbook: Tastes of a Continent by Jessica B. Harris is more hardcore.)
Beef with Bananas
Saute 1 cup chopped onion; 1 TBSP curry powder; 1 TSP salt; 1/4 TSP pepper; 1/4 TSP ginger in 2 ounces butter until light brown. (I add cayenne here, too, and/or some of my hot African pepper.)
Add two pounds cubed beef (1 inch cubes) and saute for 10 minutes.
Add 1 pound tomatoes cut into 1 inch wedges and 1 cup water; simmer 30 minutes.
Add four peeled and sliced bananas (2 inch chunks) and simmer 15 more minutes, or until the beef is cooked.
Serve with rice and braised cabbage.
