Put your oats, portion of milk, some berries, cinnamon and honey in a container and leave it in the fridge overnight.
Do it now.
Come thank me tomorrow morning once you've tried it.
I like the fact that they are more concentrated in terms of calories/nutrients per 100g than cooked oats and also provide steadier energy. I often pair them with a protein drink (pea protein + rice protein), a drizzle of avocado/olive oil, and berries. Takes just a few minutes to prepare.
Come thank me, once you've tried it. If cold stuff is your thing at all, which could be compensated with some nice green tea, or coffee, ofc.
I might be wrong, but I do think non-instant oats is more nutritious.
But to answer your question, it's a combo of laziness and taking care of future me. Nothing beats opening the fridge in the morning, groggy AF, and finding delish breakfast ready to go, and it's dirt easy to prepare with no pots to clean afterwards.
Hell, go full insanity mode and make your overnight oats with cream!
The overnight oats (rolled or steel cut) will cook much faster after they've soaked up liquid. If you're adding ingredients such as egg (two per 1/3 cup s.c. oats) this takes care of the raw elements as well.
