I have a tiny fridge so I need something I can put in my chest freezer and microwave portions of it to put in a thermos. I’m hoping for minimal prep work, though I have a Vitamix if that helps. I already eat the same thing every day, that I buy from work for 6 dollars. Not ideal. I’m thinking I can bring the soup and some crackers or something.
Not exactly soup, but congee (rice porridge) is great for filling your belly and it’s very easy to make.
I guess you could make it watery enough to pour it out of a thermos if necessary.
