Significance of eating corned beef, potatoes and cabbage on St. Patrick's Day?
Potatoes, cabbage, and boiled bacon were cheap but wholesome ingredients, easily obtainable, which provided the calories needed by a working person. Thus, the meal became a staple diet of the Irish working class. It is still popular today.

The corned beef must have replaced the bacon bit in some places because it is easier to obtain, probably even cheaper, and easier to keep and prepare.

But the meal is cheap, quick to prepare, and contains much goodness.
