Ingredients I have used:
4 oz dried figs,
4 oz raisins
4 oz dried apricots
4 oz cashew nuts
4 oz oat flakes
4 oz hazelnuts (whole or chopped)
Note: originally I have used 100 grams of each ingredient, since we use the metric system in Europe, but I have recalculated it for you. Here is a great calculator for doing so.
Chop all the ingredients (by hand or in a food processor) and pour it into a jar in which you intend to keep them and stir it by spoon or after closing the lid shake the entire jar.
Of course you can change the ingredient rates, this is the one that suits me.
And here's my result:
Of course there is a great variation of the ingredients you can use, depending on your taste, eating habits, or eventual allergies.
dried fruit - dried cranberries, prunes
nuts - walnuts, pistachio, unsalted peanuts
cereals- corn, millet, rice flakes, etc.
The possibilities are really numerous, it is just up to you to adjust them to your taste.
The ingredients mentioned above can be found in a local supermarket. You can also buy already prepared mixture of dried fruits or nuts, but in my opinion these fruits contain too much sugar.
