I always leave out the bread since I almost never eat bread and I try to be healthy or something..Thinner slices of cheese seem to do better with this, not large chunks. or grating works too. I tend to use cheddar. I think using sea salt always makes a big difference. Pepper doesn't do much for me, so I skipped that. I like the idea of adding something fancy, like truffle oil. As for the "where's the bacon?" comment I received, feel free to add some bacon!
Yes, it's true. When you make food for yourself, it does tend to be better than paying others to make a generalized version of what they think people want.
My version of egg-and-cheese (most of it stolen and some of the original left out; the original link is available above):
