Do you live near a Trader Joe's? Trader Joe's has a delightfully large selection of oats and other hot cereals. You can find quick cooking steel cut oats (cook in 8 mins, which is indeed fast for steel cut oats). My current favorite is TJ's multigrain hot cereal. There are also multiple varieties of oatmeals that come in single serve packs (and are still relatively healthy/low sugar). TJ's also sells single serve oatmeal packages in the freezer section. Can't go wrong with Trader Joe's! (and no, I don't work there...I'm just obsessed).
