The sets themselves are a little weird, since the food scales really well with 1/12 figures, but often times there's also furniture in the sets that are a bit too small for 1/12. Probably more along the lines of 1/18.
I think there are also a lot of little domestic blind bags/boxes/packs that have different food items.
You can also go into craft stores and find little food items and other accessories. I think they're more meant for dolls, but they work perfectly well for 1/12 figures too.
