I do oatmeal in 2.5 minutes in the microwave. 1/2 cup oatmeal, 1 cup water, 2 tablespoons ground flax seed (for healthy fat, protein, Omega 3s and so forth), a little cinnamon and about 1/3 cup of frozen berries (I buy the mixed berry package, but you can do blueberries or whatever else you like. They thaw while the oatmeal cooks). You could throw in some slices or slivered almonds too, for protein and healthy fat. Sometimes I put a little raw sugar in it and a tablespoon or 2 of coconut oil (per my orthopedist), which melts during the cooking and gives a nice tropical taste. It takes 30 seconds to assemble because I keep all the ingredients together except the berries. I don't add milk, but a lot of people do that or add soy or almond milk.
I agree that eggs take no time. You could also make a frittata or quiche and just heat up a wedge in the morning. It's a great way to add vegetables too, if you use chopped spinach or tomatoes or asparagus, whatever you like.
You could put peanut butter or cashew butter on a slice of toast with the frittata too.
