Eggs: just like meat, the type of fat in the yolks is largely dependent on what the animal ate and what kind of life it lived. If you can get local, pasture-raised eggs, they're much higher in Omega 3s and don't tend to raise your LDL cholesterol nearly as much. Hens are so easy to raise that almost everyone, even in suburbs and exurbs, can find a local farmer. (Most cities are easy because they usually have thriving farmer's markets. And for the record, hens do need supplemental feed to lay regularly, so they won't be entirely pasture-fed, but you may be able to find a farmer who feeds only local organic grain.)

I still wouldn't eat any animal product every day. Unfortunately, "organic" and so-called "free-range" mass-produced grocery store eggs are almost always factory farmed, so avoid those as well if cholesterol or animal welfare are issues for you.

Oatmeal, or any grain cereal, is easy to make ahead and keep in the fridge for several days. If additives are your only concern, "quick oats" are basically shredded, with no sugar or other additives, and they'll cook up in 1-2 minutes. Or you can microwave old fashioned oats for 6 minutes on 50% power without stirring, just make sure you use a large enough container so it doesn't boil over. I use a 4 cup container for 1/2 cup of raw oats, but if your water is softened or naturally very soft, you may need a much larger container.
