Grab a frying pan, add a drizzle of oil and get it on the heat. Add the oil and fry for a few minutes. If you're not a fan of sunny side up, flip it over and cook on the other side for an extra 30 seconds or so.

Toast the bread in a toaster or under the grill.

Scoop out the avocado and smash it up with a fork. Season with salt and pepper before adding a drizzle of lemon juice.

Spread the smashed avocado onto the toast and top with the egg.
