Remove smoke herring from package and soak for 45 minutes in boiling water.
While fish is soaking begin to prepare your other ingredients.
Drain smoked herring and search through smoked herring for excess bones and remove ( you will not get all the bones out, but they are small an thin enough to swallow).
In frying pan put two tbsp of oil or any fat you prefer- when oil becomes very hot throw in onion, garlic, and pepper.
Saute for one minute- Add in smoked herrings pieces and saute for 3-5 minutes till onions become translucent.
Add in tomatoes and rookoo if using, continue to cook for another 3-5 minutes.
All finished, enjoy with dhal and rice or just rice alone.
If the smoked herring is too hot a little brown sugar added in will help cool the fire.
