I dont use instant oatmeal but use coarse cut oatflakes mixed with different type of flakes and some hot water. I then add lemon juice, a fruit yoghourt, a grated apple, some milk to get the right consistency. And then just any type of fruit depending on my mood such as berries, pineapple, mango etc. I also sometimes add nuts or raisins.
This thread inspired me to try with cinammon.
