When I stopped keeping kosher and before I started adhering to a paleo-style diet, there were a brief few months when I ate many sandwiches. I’ve always loved bread, and the combination of bread and meat and spreads satisfied all of my cravings.
Surprisingly, bread wasn’t that hard for me to give up, from a cravings perspective. However, sometimes there’s nothing like a sandwich for a quick meal. In grad school, I practically lived on variations of grilled cheese when I had little money or time. As an adult, I’ve missed the convenience of those meals.
