First of all, pick through your broad beans. Remove the beans from the larger pods and with the smaller ones, cut them into roughly one inch pieces.
Gently heat your olive oil in a frying pan and add your onion.
Meanwhile, take your sucuk, cut into quarters lengthways and remove the outer skin.
Now cut each strip of sucuk into rough bite-sized chunks and, once your onion is sweating, add your sucuk to the pan.
Stir around for a couple of minutes until your sucuk starts to colour and release its juices.
Now add your tomatoes, garlic and salt & pepper.
Stir around and then allow your tomatoes to cook down for around 5 minutes before adding the hot water.
Stir this and then add your broad beans to the pan, also.
Now add your sugar & vinegar, stir around and taste the sauce.
Add more of whatever you think is necessary.
Leave your sucuk and broad beans to simmer, uncovered, for around 15 minutes.
Remove from the heat, allow to cool a little and then serve.
