It's mostly the wine part that doesn't sound good (I really don't like wine). Low carb tortilla does sound like something worth looking into. Although I don't like a lot of the sliced meats for use on bread and such at the local supermarket. There are a few that are pretty good, though. Sliced minced meat/meatloaf/something like that and there's some bacon with nice spices. And the dinner sounds simple enough.
By the way, do you think this book is any good? http://www.amazon.com/Low-Carb-High-Fat-Bread/dp/162914410X
Low carb bread with peanut butter sounds to me like something that could work.
