Nancy, the Reuben sounds wonderful!
But using a lettuce leaf does not.
Buying a whole head of iceberg lettuce to make 1 sandwich seems wasteful.
Perhaps an almond flour wrap might substitute?
Made open faced and melting the cheese over the corned beef in microwave? then adding the sauerkraut?
How much corned beef do you figure for one sandwich?
I tend to be heavy handed with amounts
Thanks again for the idea
Then folding over?
