So my new challenge to myself is to find soups that are 4-Hour friendly but I enjoy. My top two lately have been:
Edward & Son's Miso soup - This one can be found in most supermarkets (because if my Kroger has it, so does yours) but it hides in the organic section. It has 7 grams of Carbs and you can make with hot water from your office coffee maker. I'm also a sucker for Miso Soup
Gazpacho - There are like a million different ways to make this, but either way you blend it (ha!) it's just veggies in a food processor. Tomatoes can get your carb count up (I saw from 4g to 7g on the web per serving) so make sure you incorporate plenty of other veggies like peppers and cucumbers so you don't end up with more carbs than you planned.
