No good on canned soup - but try this... it takes about 5 minutes to prepare!
Make up a stock using boiling water and a stock cube or some fresh stock...
Add baby vegetables of your choice, plus any seasonings (I use fresh ground black pepper and a good dollop of whole-grain mustard)... boil for about 3-4 mins... switch heat off... leave to cool a bit and serve... YUM!
To thicken it up, add:
red lentils (takes another 30 mins to cook)... or
diced potato (takes another 6-7 mins)
To snaz it up: Sprinkle with fresh herbs (parsley and basil are best)
Play around with this and add what you like - chunks of cooked chicken, beans, etc etc
Lo cal, and only contains as much salt as you add yourself.
