Toasted Potato & Beet Sandwich

A delicious toasted sandwich made with leftover potatoes, herbs, beetroot and sweetcorn.


To celebrate turning 100 Hellmann's decided to challenge bloggers to minimise the amount of food waste thrown out by using their leftovers in sandwiches.

Their 'Sandwich of the Century' challenge is part of their Love Food Hate Waste campaign.

I'm always up for a challenge, so I decided to make a new sandwich using my leftovers. I saved leftover potatoes from our evening meal and came up with this tasty toasted sandwich.


To create my toastie, I looked in the fridge, to see what I could use up. 

No specially bought ingredients for this lunchtime snack.

I had some leftover cooked potatoes in the fridge and thought why not! I dressed them in dill flavoured mayonnaise, mixed with spring onions.

Alongside the potato I added pickled baby beets for a little piquancy and little pockets of sweetness courtesy of some leftover sweetcorn.

Seasoned  it all with black pepper and toasted until crisp.


I would never have thought to add potato to a sandwich before but it was amazing and such a comforting lunch.

This sandwich is a triumph! It just shows you what you can do with leftovers, so there's no excuse.

Note to self: must try harder!

Disclosure: Hellmanns asked if I would take part in this challenge & sent me a bottle of mayonnaise to use in my recipe. I was not required to write a positive review and any opinions expressed are my own.
