Thanks, and that’s a hard no to ever getting one.
A waffle maker will toast buns, does a great job on hash browns, can make funky looking eggs and bacon. It can even do waffles 
We had this growing up. We made hundreds of toast tites with bread, butter, egg, diced spam, and American cheese. The egg took up most of the space so they were always light on the meat and cheese. I bought one a couple years ago and using it was a bigger pain in the ass than I remembered.
An authentic Long Island egg sandwich. 2 eggs, bacon, cheese, ketchup, salt, pepper, on a fresh kaiser roll. Never found any place outside of NY that made anything that tasted remotely as good. Even when I’ve tried to make them. No idea why. I’m craving one now.
Someone gifted me a breakfast sandwich contraption about 20 years ago - a two-slice toaster with an egg poaching cup and sausage warming tray built in. I remember it took a bit of experimentation to get the timing figured out so everything ended up done just right at the same time, but at that point it was quite useful.
The key bit of prep was to pre-cook the sausage patties. Experimenting again, I discovered that extremely thin patties were just as satisfying as thicker ones and I could get 16 from a pound of sausage. They cooked almost instantly when they were that thin too, so the prep wasn’t too onerous.
Eventually I moved away from breakfast altogether. I have no idea what happened to that thing.
There was a time for me when the perfect breakfast sandwich was two slices of cold combo pizza, one flipped over onto the other, to make a sandwich. To make it a perfect lunch sandwich, all you needed to do was to warm the pizza slices up a bit, preferably in a pan or toaster oven, not microwave. Now, however, it’s a SPAM (gochujang or tocino flavor), egg, and cheese sandwich on a sourdough English muffin. In the summer, add a slice of fresh-from-the-garden tomato.
To clarify: for me, they can absolutely be a full breakfast. I don’t need to augment to be satisfied. There is something that just doesn’t feel like a meal about a breakfast sandwich I could use one hand to hold and eat. Because of the number of bites. Separate the sandwich into its parts- toast/muffin, eggs, meat- and put them all on a plate side-by-side and it would be more meal-like. Psychology, not nutrition.
Similarly, for whatever arbitrary reason I’ve got in my personal food taxonomy, a bagel with cream cheese is not a breakfast sandwich, even though it is often eaten for breakfast. I think egg is the defining characteristic. Similarly, I’ve seen places serve “breakfast” pizzas or flatbreads, and egg is the consistent ingredient. Take a food category like sandwich (or pizza, or taco), prepend the word breakfast, and you are advertising that eggs are involved.
I can’t believe I read through this whole thread without seeing the McDonald’s Sausage egg and cheese McGriddle! It is currently the gold standard of fast food breakfast sandwiches IMHO. It is my go-to breakfast sandwich on Saturday mornings, which is really the only day I eat breakfast.
Gotta rep my hood. Pork roll, egg and cheese on a hard roll. Many people put ketchup on it but I hate the idea of ketchup and eggs. It’s all about the balance. I see too many posts with people bragging about their PEC with ten slices of pork roll. Way too much. It overwhelms the sandwich. Two or three slices at most. Always well done. The salty taste and crunchy feel go perfect with the fried egg and cheese. Can be cheddar but American melts better. The hard roll is key. It isn’t a Kaiser roll although it could be called a variation of one. An authentic hard roll is baked slightly different and has a crunchier outer layer. The same on a good bagel also works.
Hardee’s used to make what they called a Frisco breakfast sandwich – basically an egg McMuffin with two slices of sourdough toast instead of the English muffin. I usually ordered sausage on mine. Much better IMO than the McD’s offerings.
There was a place in Lafayette IN back in the '80s that served the following sandwich:
– a slice of toast
– bacon, ham or sausage
– a fried egg
– a second slice of toast
– bacon (optional)
– cheese
– a hamburger patty
– mustard, ketchup, and/or mayo (optional)
– a third slice of toast
It does have its own song.
sorry, for me it’s the Steak and egg on muffin/bagel/biscuit (I rejoiced when they brought it back!),
