Soups can be and often are some of my favourite CR meals. I don't think I ever expected that.
First of all soups were never really all that filling for me in the past. I still don't much care for smoothies that are too smooth for just that reason. Anyways, with the CRON approach there are generally lots of vegetables in your soup and they get to be really filling as there aren't a lot of calories in turnip, cauliflower, kale, onions, and the like.
Second I thought soups were too much of a fuss. However, my 30 to 40 minute soups now become my planned over meals. They are so easy to split into multiple servings and store in the fridge or freezer (on occasion). So 30 or 40 minutes is actually for 4 or 5 meals which is a time savings.
Third thing about soups is that when I make my own I can customize it for the tastes, textures (I like garbanzo beans), and various other things like weird chemicals mixed in with your soup base. Lately I use miso paste in place of bouillon. With the wather getting warmer I was even thinking about cold gezpacho soups.
Calories are another thing that is customized. Depending on the soup I may store it in containers as a smaller midmeal or as a larger regular meal. Voila! Serving size and calories easily "contained" so to speak.
All of these things keep me and my CRON-o-Meter happy with soups. Not to sound like an infomercial but "Try one today!"
