re: Using frozen chopped veggies as a shortcut

Well, both I guess. The latter, more for freshness sake. Often I'll buy fresh vegetables, only to have plans change during the week and then they sit in the fridge too long. I now get frozen green beans, asparagus, cut spinach, broccoli, and peas.

But yeah I was asking about the seasoning blends or just plain old frozen chopped onions or carrots, for use as a mirepoix, to save time on chopping.
