My kids were quite young and I was a single, working mom! Trying to come up with dinner every night after work without caving for fast food was sometimes a chore.
I created this easy to make pizza/sandwich/roll up one night and my kids went wild for it.
They named it - Yum Yum. LOL! And hence the Ham and Cheese Yum Yum was created!
I hope your family enjoys it as much as my kids.
