Me and mine have various food sensitivities (latex, nightshades, pork). I use an android app “fig” to check things at the grocery store–scan the barcode and Fig tells me who shouldn’t eat it and why. It does smart things like label “spices” as yellow because maybe it’s peppers maybe it’s not. The free version is sufficient for one person. The paid version lets you add more profiles.
It is hard to find onion-free chicken stock. My dog goes nuts for chicken but is a fussy eater otherwise, so we’re always on the lookout for dog-friendly stock to add to his kibble.
I don’t eat pig and Applebee’s adds bacon to their Mac and cheese. They list like 8 different cheeses in the description but don’t mention the bacon. Parents didn’t want me to make a fuss so I ate it. That was not fun. (This was years ago, ymmv, I don’t talk to those parents anymore because reasons.)
