First, I hope you read the entire book.  If you are about to embark on the 30 day, almost 0 carbs a day, program, then your choices are limited.  You can substitute meats, or soy based breakfast products.   
I would also like to share with you something that I do to replace sandwiches.  I get large leafed greens, collards , mustard greens.  I put my meat , cheese, condiments, in the middle of a large leaf and then roll them into like a green burrito.   
The heavy greens leafed vegetables are real important.  If you dont eat the green veggies, high in fiber and low in sugar or starch , your sugar cravings will be much greater. 
I am not on a diet, for me its real simple, if i want to stay below 250 pounds I cant eat
bread
starchy foods
foods containing sugar, corn starch or corn syrup if these items are in top 4  of the ingredient list. 
If I dont eat plenty of greens , its very hard for me to avoid the above. 
Other things I have learned:
Dont trust labels - sugar free , dose not mean 0 carbs, they cont have to report starches as sugar on the label, yet it turns into sugar very quickly in your body.
Sugar free candy and sugar free soda - if you are trying to lose weight , these may bring you out of Ketosis, its real important to use your keytone strips, as Dr. Atkins points out, to tell how your body reacts to different foods and combination of foods. 
*sugar free candies use sugar alcohols, these will cause you gastric distress., nothing permanent but can be embarrassing. 
You will find over time you can tolerant foods that are low glycemic, some fruits and berries, etc. 
I am a sugarholic, I wish you good luck in your quest for better health.
