Do you love those little deli pots of cheese and onion sandwich filling sold in the supermarkets? If you do, then this post is for you - you can make an even more delicious sandwich filling at two thirds of the price!
Finely chop the onion, and spring onion leaf if using
20 g onion
Mix with the mayonnaise and waterI found that the mixture definitely needed a bit of moisture to make it spreadable, hence the water
2 tblsp mayonnaise, 3 tblsp water
Assemble
Once ready to eat, spread a quarter 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. 10 slices bread
10 slices bread
This mixture does not freeze well, so it is not recommended.
Notes
How to store homemade cheese and onion sandwich filling
This will sit happily in the fridge in a covered container for 5-6 days.
Will this filling freeze?
Unfortunately, mayonnaise tends to split and go watery if frozen, so this filling won't freeze very well and is not recommended. Also, onions may well go mushy when defrosted.
What other ingredients could be used in a homemade cheese and onion filling?
Vary the flavour of the mayonnaise. Most supermarkets have several different flavours available
add some mustard, Dijon would work well
A little dollop of mango chutney would be delicious in this
Add a little finely chopped vegetable
very finely sliced celery
grated carrot
fine chopped black olives
add some fresh spinach leaves, lettuce or good old iceberg
vary the bread, dependent on what you have in - sourdough, granary, floury baps, wraps or anything else you fancy
add some sliced gherkins
swap the mayonnaise for soft cheese for a different flavour
What else can I use this for
You might not want four cheese and onion sandwiches, so what else can you use this mixture for?
enjoy it with pasta, either hot or cold - great for a packed lunch box, or perhaps couscous, rice or quinoa
top a baked potato with it
dip some carrot batons or pepper sticks in, for extra veg - we could all do with that!
