I discovered that this does not work only with over-priced, sugary packets of oatmeal, but it also works with bulk quick oats and old-fashioned oats, too! Here's how you do it:
1. Put on some water to boil.
2. While you're waiting for the water to boil, scoop the desired serving amount of oatmeal in the bowl you plan to eat out of. The oatmeal will expand a little, so don't fill the bowl too full!
3. When the water is boiling, pour it over the oatmeal. Be generous, because the oatmeal will absorb a lot more water than you think it would.
4. Let it sit for a couple minutes (the old-fashioned oats take just a wee bit longer). Put on all the toppings you like (I myself love cinnamon, brown sugar, and walnuts), and enjoy!
No more dirty breakfast pots! That works for me!
