In a medium skillet, melt a pat of butter over medium low heat. Crack an egg or two into the skillet and cover with lid. Let it cook until just barely set and then add about a tablespoon of water. Cover with lid again to allow to top of the egg to finish cooking, the steam helps accomplish this nicely.
While the egg is cooking, warm 2-3 heaping tablespoons of the marinara sauce on a plate in the microwave. If you are going to feed several people, it is simplest to just warm the sauce in a pan on the stove. When the eggs are done, place them on top of the warm marinara sauce. Enjoy!
