Open can of chicken and drain it making sure to get most of the water out.
Put chicken in a prep bowl and if not already shredded into small bits do so.
Start adding the mayo with a fork first but do this a little at a time while your mixing it in. You may use more than 3/4 of a cup or you may use less it just depends on what brand you use. You don't want it to be runny at all.
Add the rest of the ingredients to the bowl and mix in.
Use the fork to spread onto the bread
And enjoy
