I've been freezing for the past several months and in practice thawing just means "Set the mac and cheese/chicken fingers/chili in the fridge so it's ready tomorrow". I have about half a months worth of meals for 2 in the freezer, plus some months worth in a deep freeze in the garage. Prep and planning isn't reduced that much except for overhead like driving to/from the store, most of it is just shifted to one big cooking night.
