First forgive me for long time it took me to write a new entry. My second end-of-the-semester examination is upon me and I have quite a lot of work until my vacation starts June the 7th.
The daily meal for the common man or peasant wasn't all that interesting. Soup, porridge and bread. Usually the farmsteads had a small garden where they grew cabbage, turnips and the like. If you were close to the sea fish was also a part of the diet and wild plants like berries and nuts would be gathered. The poor did eat meat too, but it was more precious than grain.
I will recommend you to check out Daniel Myers blog: http://medievalcookery.blogspot.com/ . He also has a website: http://www.medievalcookery.com/.
Have fun in the kitchen :)
