This simple chicken mayo sandwich is quick and easy to prepare, uses a handful of simple ingredients, and is one of the most simplest of sandwiches to make.
Shred or chop the leftover cooked chicken into small pieces.
Place the chicken in a bowl and add the mayonnaise, dijon mustard, chives and mix together. Season with salt and pepper to taste.
Butter the slices of bread. (Sometimes I don't bother buttering the bread, this is up to you.)
Take one slice of bread, place a few leaves of rocket / arugula or lettuce, if using, and top with half the chicken. Top with another slice of bread.
Repeat with the rest of the bread, rocket / arugula or lettuce and chicken.
These sandwiches are best straight away.
Notes
Nutritional information is calculated without butter.The amount of salt your chicken mayo filling needs depends on whether you are using roasted chicken, or how heavily salted it was seasoned originally.Cooked chicken – leftover roast chicken, shredded rotisserie chicken, leftover poached chicken breast or baked chicken thighs – they all work in this sandwich!Mayonnaise – use a good quality egg mayonnaise such as Hellman’s, it is a creamier mayo which has more flavour. You can also use Kewpie if you prefer.Bread – soft white bread is a classic choice and I love to use it for a pure comfort food type of chicken sandwich, but wholegrain bread or even a baguette are all delicious. I would recommend against using sourdough, as I personally think this is an occasion for soft bread.Dijon Mustard – this is optional, but the slight sharpness of it cuts through the mayonnaise. You can use wholegrain mustard if you prefer.Chives – fresh chives add a mild onion flavour rather than using raw brown or red onion which can overpower the chicken sandwich filling. If you like raw onion, then feel free to use them, or add an extra flavour with some chopped sumac onions.Rocket / Arugula – this peppery leaf adds a freshness to the chicken sandwich filling which I personally love, but you can use lettuce instead or leave out altogether.If you are planning on making this sandwich to take to work or on a picnic, it is worth buttering the bread to act as a barrier and prevent soggy bread, otherwise I often don’t bother buttering the bread.
