Slow day at work, called a Dell support rep to deal with some equipment that needed to be replaced and ended up talking with them for 2 hrs. I think they must’ve been bored too because I remember telling them directly that we could end the call or keep talking if they wanted. They not only were comfortable with it but said they’ve never just chatted with someone.
Same idea as OP, it was like catching up with an old friend.
I have two suggestions: homemade pre-made, and why not both.
You can pre-make things like pancake mix, taco seasoning, pasta sauce seasoning, etc. write any instructions on the ziplock bag or container.
Instant items from a box or bag can usually be dressed up with fresh foods. If she’s cooking then offer to prep fresh items.
Also, respect that some people simple have no patience for cooking and don’t want to learn any. Communicate with each other to understand how to make it work.
