This one is a super simple and healthy breakfast idea (about 450calories). All you'll need is:
130gr. yoghurt (I use 0% fat)
120ml. milk (1,5% fat or any other you like)
25gr. oats (quick-cooking style)
15 gr. muesli with dried fruits
1 tsp linseed
1tsp stevia (optional)
Just chop up the fruit, and mix everything in a bowl. Enjoy!
