Wash and then remove the seeds from the green pepper and cut up
Clean the other vegetables and cut up
Add all the ingredients in a large enough pan, add one tsp of salt and the pepper, the bay leaf and add so much water that the vegetables are almost submersed
Bring to a simmer and simmer for almost 1 h. Check the taste and especially add salt if required
Thereafter drain through a strainer, press out and let the broth cool and freeze or use it
