Ham and egg bun is a type of sandwich that has a little bit of everything! It starts with a soft bun, like a hamburger bun, that's been cut in half. On one half of the bun, you put a slice of ham, which is kind of like a big piece of salty meat that comes from a pig. On the other half of the bun, you put a fried egg.
To fry an egg, you crack it open and let the yellow and white parts cook in a hot pan with some butter or oil. When it's all cooked, you slide it onto the bun, right on top of the ham slice. And there you have it: a ham and egg bun.
Some people like to add toppings, like cheese or ketchup, to make it even tastier! It's a yummy breakfast or lunch option that's easy to make and eat on the go.
