Yes I buy them when they are on sale. I try to only buy frozen vegetables that are flash frozen. I then use those vegetables in other dishes as a time saver to prevent having to put so much work into chopping. You could make a stir fry pretty easily using such vegetables just add soy sauce, garlic, ginger and Voila! Dinner in about 10 minutes.

Kashi also makes great frozen microwavable meals that are all natural. Great for when you need lunch on the go.
