Preferably something that has little to no preparation required.
Overnight oats which you can prepare the night before. Soak some oats in milk and keep it in the fridge for at least 2 hours for the oats to soak up all the liquids. Toss in your favourite toppings, like freshly chopped fruits, or even some chocolate, and it’s ready to eat.
Wait you mean you don’t cook the oats? Oats (the old fashioned 30 minute kind) cook nicely for me in 4 minutes in an instant pot, but no cooking sounds even better.
Cooking is not necessary for overnight oats. I used steel cut myself, but the texture of these oats prepared this way may be chewier than you expect or are used to though, if you have always been heat-cooking them.
Just look up overnight oats and there are plenty of recipes and suggestions, some even using yogurt instead of milk. Here’s one from Martha Stewart for starters,
