Welcome to Conversation with Katherine and my podcast Meat and Potatoes.  
A meat and potatoes person brings gravitas to the relationship.  They usually don't bring to the relationship trauma or drama.  They say what they mean, keep their commitments, they are reliable.  The downside is that because there is no drama and/or trauma they can be somewhat boring.

You have to be in a certain season of your life to have a genuine appreciation for this type of individual.  It could be all of the fast pace, fast living that we see in the media where all problems are solved in thirty minutes or less and love happens in under an hour with commercials. That may be why appreciation of this individual is so rare.
