I usually make things fit my trip. Things like rice, beans, salt, oils, butter, margarine are things that I ate in very limited amounts, so cutting them out almost completely was pretty easy.
Chickpeas will be tough. I like a good hummus. And I kind of like tofu, though I usually made it into a dip.
Oh, I know. Corn chips. I realize corn isn't a forbidden food, but I'm never eating corn produced in the U.S. ever again. I guess I can eat spinach dip off my finger.
Bread is tough. I'm a sandwich lover. But really, a burger with tomato and jalapenos without the bread isn't bad. By next month, I'll probably be wondering why I ever masked the flavors with bread.
