I hope you enjoy it as much as we do!
You bet you can have soups on this program! The book has a few recipies for soups, but just about any soup will do as long as it's components are sonoma friendly (brothy soups with lean meats-beans are excellent!- and tier 1 or tier 2 veggies-depending on your wave) I would even say you can have your crackers as long as they are whole-grain with at least 2 grams of fiber. They would count as your grain for the meal!
good luck barb!
