The ingredients to make salad are actually pretty affordable (depends on where you purchase it of course!)
A healthy salad is easy to prepare, e.g. here's one of my favourite: Cucumber, Carrot, Celery - slice thick julienne style. Layer it with whatever cabbage you fancy. Put it in a cup instead of plate if there are visitors over.. so it looks more "attractive/tantalizing" like a pretty flower.
I prefer to wash my veges. using baking soda & vinegar or those organic vege. washer. Just soak them thru and run over water a few times.
Some of my friend prefer to blanch it with hot salt water.
As for my favourite dibs:- yoghurt mixed with pepper, smashed smoke garlic, paprika & a bit of salt.
The amount of time required to prepare this is less than 20mins., but if you were to order it at a restaurant it could easily cost RM10-20+ & it's not even crunchy fresh.
So budget wise. Learn to DIY :)
