There's a dueterocanonical text discovered among the Nag Hammadi that recounts Cains story after murdering his brother in 4153 BC. In the scroll, textual critics and Old Testament scholars believe that after marrying, Cain fathered 5- not 4- sons: Enoch, Olad, Lizpha, Fosal, and Matt.
While his first four brothers lived recklessly (Enoch was famously canceled for something his great great grandson said about paying revenge back 77x), Matt, an avid chef and bread baker, dedicated his life to the Lord.
In 4068 BC, after decades of obsessive craftsmanship and iterative experiments, Matt offered up a burnt offering to surpass all burnt offerings. It was a sandwich the likes of which our young planet had never seen. A sandwich that shook the nations, cured hunger, and brought down heavenly blessings of love and faithfulness to Matt's family for a thousand generations.
It was the Matt Cain.
Matt died seconds later, of course, as creating this sandwich had cost his weathered body everything. However, his magnum opus lives on to this day - a beautiful synthesis of fresh ingredients and warm crusty bread. The Matt Cain is the kind of sandwich that brings tears to your eyes as you find yourself yearning for heaven. The kind of sandwich that evokes nostalgia for a time long since forgotten. A time when you weren't procrastinating from your studies while writing a review that nobody would ever read.
Tldr: 5/5, will have to try some of the other sandwiches
