Learn English – Is it right to say “a multi-vegetable salad”

To me, there is a subtle difference in meaning here:

You are multi-tasked woman.

This states that the woman often/always has multiple tasks simultaneously assigned to her for completion, whether or not she is capable of doing so, whereas:

You are multitasking woman.

is a statement that the woman in question is currently in the act of completing multiple tasks at once, which carries some implication that she is capable of doing so. Furthermore, this may have been intended as:

You are [a] multitasking woman.

which would imply to me that the woman in question is seen to have some tangible capability to handle multiple tasks at once.

In British English, veggie means vegetarian (at least according to the Collins Dictionary). It can also be an adjective which is used to talk about food that doesn't contain any meat or fish: Going veggie can be tasty, easy and healthy too. Veg is an informal British word which means a vegetable or vegetables: I like both fruit and veg.

In American English veggie means vegetable first of all. But of course it is more informal than vegetable: ...well-balanced meals of fresh fruit and veggies, chicken, fish, pasta, and no red meat.

So, if you want to use veggie right, mind the regional differences and and the level of formality appropriate to your situation.
