Hmmm... I believe that there is one small company near where I live that sells bulk Paleo frozen meals. I'm not sure if there are many in general, though.
Maybe you could get together with your friend and take one day out of the week and show her some basic recipes? Show her how to hard boil some eggs, how to fry some ground beef, how to steam/boil some veggies, etc. If she doesn't know how to cook, then maybe she feels a bit overwhelmed by the thought of having to cook 100% of her meals from now on. Show her just a few basic recipes.
If she knows how to cook, then she can make her food for the week and just freeze it. It's pretty easy to make a large batch of chicken wings and freeze them. I think sweet potatoes might also do well in the freezer. Pretty much any veggie that doesn't contain a lot of water will probably do good in the freezer. Also, hard boiled eggs stay good for up to a week in the fridge.
If your friend just doesn't like cooking at all or has no time to cook, then for the time being I think it's perfectly okay to buy some healthy packaged food. Canned fish such as tuna, salmon, and sardines taste really yummy. And you don't even need to cook them. Smoked salmon is also yummy. Canned veggies are also a decent option. They also sell frozen vegetables in bags that you stick in the microwave and it steams the vegetables. That's a really quick option as well.
Hope I helped!
