I always feel very happy with myself whenever i make use of those odd bits-and-bobs in the cupboard or the fridge. Its obviously a good thing not to waste food, although we are all sometimes guilty of it.
So anyway, when white sliced bread is going a bit stale, simply cut the crusts off with a knife, tear the bread up a bit and put it in the blender with some parsley. Makes good breadcrumbs with lots of flavour and the colour is amazing. For an example of how to make use of these, try drying out fresh white fish (like cod or coley fillets) with kitchen towels. Next rub with olive oil and a little salt and pepper....coat in the herby breadcrumbs and bake in a hot oven for about 8-10mins.
There's more. Don't throw the bread crusts away. Cut those into croutons, spread out on a baking sheet lightly coated in olive oil. Add a bit of garlic salt and black pepper and bake in a hot oven until they are golden and crisp....great to put in the soup you make as a starter before you eat the herb encrusted white fish.
