Diary Free recipes- Warning very fussy eater!

Just about any meal from a country further east than India.

If your problem is only glucose intolerance you should be able to handle milk products where bacteria has already digested the glucose. That includes yoghurt and most cheeses.

In addition to what acpgee said (I was thinking the same - though I'm assuming they meant lactose, not glucose), there are a ton of dishes from the Indian subcontinent that would fit as long as they don't have lentils. Honestly there's a lot of recipes in general that would fit the bill.

I don't eat most dairy products nor avocado and haven't really had many issues finding recipes from around the world that work. Various dishes from the Caribbean would work (as long as you didn't cook seafood dishes), from the Americas more broadly, there are plenty of dishes from all over Europe that fit the bill, etc. Just looking at some of the tabs I already have up:

I meant lactose, not glucose indeed. Thanks @aokaye.
