This is a recipe I learnt in Home Ec in high school. It's one of my favourite quick meals to cook. None of the ingredient measures are precise. Approximate will do. I normally omit the capsicum because I normally don't have any. If you use a good quality canned tomato soup in normally tastes better.
I've also made it with other types of mince (kangaroo, pork, lamb) - but it tastes best with beef.
