Remove 1 tablespoon of tomato sauce from the can to be used later. Then blend the ingredients for the pepper sauce (green pepper through caradamon) in a food processor until there are no chunks left. Set aside.
Pour the oil into a pressure cooker, sprinkle the beef with salt & pepper then brown over medium heat. Once brown add the water, reserve tomato sauce, paprika & cumin. Seal with the lid & cook for 10 minutes (after it begins to hiss). Note: If using a regular pot you should cook the beef for 30 minutes.
Once the beef is done cooking pour it & the any sauce into a regular pot. Add the pepper mixture, sliced onions & green peppers, cover with a lid & simmer over medium-low heat for another 30 minutes. It is done once the vegetables are tender.
