I like granola, I just buy whatever I fancy and add to it whatever I want. Sometimes it's full fat greek yoghurt, fat free, dried fruits, fresh fruits, nuts, seeds, fresh fruit. Better than some cereal, worse than others but it tastes nice.
It doesn't keep me full for very long though but definitely fuller than toast or coco pops!
I also eat porridge made with milk, add in fruit, seeds, protein powder and a bit of honey or maple syrup (not the proper stuff 😱) Bit more filling than granola.
Eggs is also a go to, poached on brown sourdough with avacado and with or without prosciutto ham, smoked salmon, spinach. Keeps me fuller for longer than the above breakfasts.
If you like granola then eat it, don't eat too much.
