Not a veggie pot, but I make my own version of them instant porridges that are well expensive. Take one to work each morning for breakfast and normally sees me good from around 7:00 am till lunchtime.
Small tupperware type box with lid.
4 tablespoons of porridge oats
1 tablespoon milk powder
sugar/salt to taste
Add anything else you want. Currently I’m into a dollop of peanut butter.
Get to work and add water from boiled kettle to approx 2x height (eg porridge 2cm in pot, fill water to around 4cm) Stir for a few seconds, pop lid back on and leave for 5-10 minutes. Remove lid stir again and enjoy.
