– 1-3 instant oatmeal packets
– A glass cup
– A stir stick
– That stupidly-small single-serve coffee machine
– Optionally, packets of sugar or creamer
Remove the coffee filter from the machine. Fill it with slightly more water than requested on the oatmeal packet; the glass cup can double as a crude measuring device. Empty the packet into the glass cup, place it in the machine, and start brewing. Stir the mixture while the water dribbles in, if possible. If you poured in too much water, carefully use the towel to remove the cup then catch the remaining outflow. Stir in creamer or sugar, to taste.
Repeat for each packet. Working in the bathroom make cleanup much easier. Clean the cup well, otherwise housekeeping may not replace it.
