I was alerted to sweet and sour meals by an article in the Sunday Times which found that a sweet and sour ready meal had more sugar in it than a chocolate bar and many others were extremely high in sugar.
A quick scan of frozen ready meals in my local supermarket did not reveal such shocking results but this jar did.
Water
This tells us that the biggest ingredient in this jar is actually water.
Vegetables (carrot, onion, capsicum, baby corn)
You can see quite clear chunks of these vegetables in the mix but there doesn't seem to be a lot of them.
