Canapes presented

I did start preparing this dish early. However, there are some things I can improve on.
1) The bread should be toasted before putting anything on it, so that it is not soggy.
2) Less margarine should be spread.
3) Tuna is too ordinary a filling to be used, so it should not be one of them.
4) More seasoning should be used on the chicken. As compared to the prawn, it tasted a little bland.
5) Let the toasts cool before packing them so that they don't stick together.

I guess they were not really canapes because I didn't cut the slices of bread into small patterns. I used the slices as they were. They were more like mini pizzas. :S
