The ingredients are for one serving, scale as appropriate. I started making this because I had all the ingredients. I am not sure how authentic it is. For reference, here is another recipe. Like most of the my recipes it is really cheap to make and takes only a few minutes - 10 at the most for a single serving. For the Enchilada sauce, I use canned. I have made my own, and it is better than canned, but it takes alot of work. I have tried several brands, sadly the most corporate is the one I like best: Pace. The most authentic I have tried is Las Palmas. Authentic enchilada sauce is a little bitter, it needs other things like oil and cheese to bring out the flavor. The Pace brand stuff surely has other crap in it - sweetener, color, etc…but it is tasty.
Nothin' to it, it is done. Good in the morning with hot coffee.
You can omit the cheese. If you are making many servings, it is easiest to heat everything on the stove top and get a production line going. If you are making a single serving, you can slap it all together (except the eggs, those should be fried manually) and then nuke it in the microwave for a minute or two.
