Not an egg mcmuffin at all, but for meal prepped breakfasts, I usually make a bunch of steamed buns or dumplings and have them with soup and rice, all 3 quick and easy to heat up in the morning and can be prepped ahead of time.

Though I admit it might not be as quick as an egg sandwich to eat. These days I’ve been having muesli and cottage cheese. Again, maybe slower to eat, but the prep time is about as long as it takes to take a half cup scoop of two things 😁
