Home-Made, Roasted Granola / Muesli

My husband and I used to buy various breakfast-‘muesli’ options every week: ready made muesli mix, wheat-bix, cornflakes and more…
Even though we were trying to stay on the healthy side of things, we struggled with sinus issues and finding a muesli that was affordable and yummy, yet free of additives, preservatives, sugar and the like.
