Well u can also try french dressing for ur salad.
Add some olive oil into french dressing

As for ingredients
lettuce
pepper
cucumber
tomato
croutons
bacon crisp
parmesan cheese

I guess salad is one of the easiest things to prepare
its just the sauce .. u can prepare few types of sauce n let them mix it
coz everyone might have diffrent taste. mayo is also optional but i prefer jap mayo.

yeah normally jusco have it or u can go to jap corners in cold storage or other supermarkets .. normally they sell it in the jap products section but definately jusco is selling it
