Chop the tomatoes to about the same size as whatever white bean you have. Combine everything up to the salt & pepper; taste for seasoning then add the vinegar. Cover and keep at room temp til you're ready to serve. Put some greens on individual plates, top with beans and some shavings of cheese. Serve with bread. Have balsamic & oil on the table.
