Trying to regrow lettuce

I don't know about anyone else, but we've found grocery costs to have climbed considerably since the Coronavirus shutdown has occurred.  There have also been a number of shortages as well.

To try to address both issues, we've signed up for a box delivery from the Misfits Market.  For the uninitiated it's a company that sources "local" produce from various growers who have produce that's deemed undesirable by grocery store buyers.  These are items that are fully viable for eating, but are considered to be too ugly.  Carrots with more than one root, for example.

In a recent box, we received four rooted Bibb lettuce plants in plastic bags.  We added a little water to them to keep them going for a few days before we ate the leaves in a great salad Wifey made with dinner.  When Wifey harvested the leaves, I couldn't help but wonder if I could get the root base to start sprouting additional leaves.

After a few days in potting soil we appear to have the very beginnings of a leaf or two.
