This is really awesome :D Looked for something like this a while ago and wasn't massively keen on what was already out there...

One feature I immediately tried to find, though (and then searched for a github issue for it and couldn't initially see) was to be able to filter meals by ingredients.

Not necessarily the 'fuzzy' search, but (similar to the include/exclude categories) have a drop-down list of ingredients for ingredient auto-completion and then select to add to a list of items.

And then the same for adding some ingredients that are excluded (e.g. want to do something with flour, but have no eggs)
