I love a bit of smoked mackerel and often have a pack in the fridge. This week, I made this simply gorgeous sandwich with some of it, a hard boiled and egg and a slick of mayonnaise. I’d got some hotdog rolls on yellow sticker, so stuffed the mix into there. Oh my – SO good!

What do I need to make a smoked mackerel and egg sandwich?

For 2-3 servings

• some lovely thick sliced bread
• a fillet of smoked mackerel
• a couple of eggs
• mayonnaise, expensive or own brand, doesn’t seem to matter much

How do I make a smoked mackerel sandwich filling?

• strip the fish fillet of its skin and flake into a bowl
• boil a couple of eggs for 5 minutes and once cold, peel, and add them to the fish, giving them a bit of a chop along the way
• add the mayonnaise to the mixing bowl
• give everything a thorough mix
• that’s it, store, covered, in the fridge until needed. It will keep in the fridge for 3-4 days

 

• once ready to eat, spread a third to a half of the mix onto a slice of thick cut bread, top with the other slice, cut in half and eat, or wrap ready for packed lunch time
• there’s no need for butter or anything else

 

How to store a smoked mackerel sandwich

In the fridge in an airtight container, this mix will sit quite happily for 3 days. It must be covered as the fish has quite a strong smell.

This filling will not freeze well, so is not recommended
