You can order bread mix (and some other mixes) from Bob's Red Mill. We used his stuff, but it does have a different flavor - we noticed it mostly when making chocolate chip cookies.
For lunch, I used to take all the stuff I would put in sandwiches, meat, lettuce, tomato, etc. and make them into little rolls. I also used to make a lot of stir fry or meatloaf. Zucchini lasagna is also really good, but I don't know how to make it.
I did better on that diet (I did it for depression), but I will not lie - it is REALLY hard. And after a week, I craved a Whopper like you wouldn't believe. I ate it and went back on the diet, but when I went to my parents' house for Thanksgiving, my family thought I was silly and my diet was ruined. Just beware that this time of year is going to be the worst. Plus, my husband still wanted bread and sandwiches, so I had to buy it for him. And my daughter's daycare/school could not accommodate the diet (they always had crackers for snacks).
Good luck!
