As an aside, I am going to try to make a pita out of cauliflower and cheese for a pastrami sandwich.
Saw a video last week on a cauliflower pizza crust and I think it can be modified to create a pita.
I want a sandwich, but I don't want the guilt of eating bread.
Have you looked at Ezekiel 4:9 Bread? It is made from sprouted grains. I try to stick to foods with a glycemic index below 40. Ezekiel Bread is 36, so I eat it sparingly; once a week or less. There are also a lot of good low carb wraps now that would help with a sandwich fix. I understand your craving. I love a toasted bread sandwich.
Ezekiel Bread can be found in the freezer section of your store with the Vegetarian foods.
