Rolled oats are the cheapest cereal we can buy, coconut is cheap and with whatever dried fruit is in the pantry muesli can be made quite a bit cheaper than is purchased from the supermarket. I used dried apple, feijoa and figs I have done myself with the addition of a handful of dates chopped finely. The walnuts were grown locally and purchased for a very good price, the only things worth any expense were pumpkin and sunflower seeds, which are optional.
7 cups of rolled oats
1 cup of coconut
Mix these both together in a roasting dish and melt together 4 tablespoons oil (I used rice bran) and 1 heaped tablespoon of honey (this makes just a slightly sweetened version). Place in a preheated oven at 175 deg and bake for around 20 minutes, stirring often. Bake only till golden brown taking care to mix well each stir so as not to scorch. Note that this will continue to brown a little once removed from the oven.
Add whatever dried fruit, nuts and seeds (long thread coconut is nice added here too) you like to this basic mix and leave to cool before storing. If the dried fruit is added before cooking they will turn as hard as stones…! Dried apricots and slivered almonds used to be a favourite but now I just stick to what I can grow myself.
