Interesting sandwich fillings

[The[cookie]Doctor]

If you're after something moreso in the toasted variety i can recommend,

Satay chicken toasted s/w...
Leftovers from a meal often make excellent toastie fillings.

Also a toasted favourite is:
Dolmio sauce spread on the one side of the bread
Cheese, Mushroom, Capsicum, Onion
And depending what you like, salami or ham works really well.

Oh and a favouirte from an old cafe back home used to charge $10 for a toasted sandwich,

Plain tuna, mixed with mayo and spring onions. It's really delish.
Also works well as a plain sandwich, on toast, as a volauvent filling for party fillers. Vv versatile.
