Take photos of the inside of your cabinets, fridge, and freezer after you have stocked them, and text the pictures to her.
Then she'll be able to find at least some stuff.
Personally, I like to cook. I am also exhausted at the end of the day. An hour of prep is 50 minutes too many on most days.
Something similar could be happening with her. Or not. Not everyone is into big-time cooking. Like Mame said, make 2x the food and eat the leftovers the following day.
If that's going to mean she never cooks, well, isn't that kind of the point? If her cooking is awful, then the fewer times you have to eat it, the better.
If you simply must keep score to make sure she's doing something else around the house if she's no longer cooking, hand over the laundry to her and call it a day.
PS complaining ceaselessly when someone does something for you will eventually make them so uninterested in doing that for you, that many people will just plain do it badly.
You're allowed to dislike things, of course! But if your only response to any effort is to knock it, then you'll start to see less and less effort.
