I make my own muesli - always make two big mixing bowls full which then keep OH and I going for a month or so. Mix started out as amalgamation of Nigella's granola recipe, eat to beat the menopause recipe and whatever I managed to find in the local (so called) health food shop but has evolved into a mix that always has in it:
Oats, sunflower seeds, pumpkin seeds, pine nuts, coconut flakes, flaked almonds, hazlenuts, linseed, dates, apricots, apple, blue berries, goji berries, figs, whole banana, mango, cherries, cranberries
I have mine with greek yoghurt and OH has his with goats yoghurt.
I also makes great oaty bars for taking on walks
OH swears by it and says that he finds his cycle to work is difficult without it.
What I do need to find tho' is reliable source of good fruit that has not been soaked in/contains sugar. I completely fail to see the health benefits of a packet of dried fruit (eg cranberries) that contains 65% sugar!!!
