Shallow fry the sliced garlic in olive oil, add the thinly cut red pepper and continue to cook on a low heat until the pepper has softened. Add the chopped chard (first removing the thick stalks, which can be cooked separately for longer and added later if you wish) Mix together ensuring the chard gets a coating of the oil. Cook on a high heat for about 3-4 minutes . Serve on its own as a healthy dish or as an accompaniment.
I have not added quantities as I believe it is a matter of experimenting to get the flavour you prefer, for example I love lots and lots of garlic.
