Honestly... I would suggest starting to cook extra at dinner. Then package it up along with snacks on "her" shelf on the fridge that he can just grab and zap. Ditto... it's pretty easy to scramble some eggs or make breakfast the night before.
One of the advantages of dinner leftovers... is that you know she'll eat it... and you can do the 'travel the world' thing (young childrens brains categorize new chemicals as posionous and have a gag-yuck-spit response starting at apx age 2... You want to introduce as MANY spices, herbs, proteins, etc as possible between ages 1 and 2. DON'T fall into the trap of "bland toddler food" that only has about 11 ingredients... or you'll be serving those ingredients to your "picky eater" until age 5 or 6 when the neurological response shuts down. Curries, soups, mesoamerican, chinese, italian... cook as MUCH as you can -and order in as much as possible- over the next few months. Just keep the star rating at 0-1, but make sure what she's eating is LOADED with herbs and spices and sauces and and and).
The downside to cooking ahead of time / Coming up with new things means he's the one experimenting with new foods. And if she rejects it will be turning to the one or two favorites (hot pockets, macncheese) and you're going to end up stuck with those things / in arguments with him about her diet.
