Once again... faced with the start of school, and kids (and parents) who can't eat A, B or C. My solution - switch cultures. No meat makes no sense when eating middle American Cuisine. Vegetarians and Texa BBQ just aren't friends. But cooking non-meat substances over smoke and infusing it with a tangy sauce... Sure just check things out a few time zones over - the Japanese have their own version. Or Viet Nam, or Thailand.... and then when you get to India the choices are so vast as to be overwhelming!
One of the most surprising best things I ever had was an onion bhaji where the onion had been smoked 1st. The tamarind based dipping sauce with lots of cumin was the perfect compliment.
(Onion Bhaji is for lack of a better description Indian Tempura. This is often made with a besan (chick pea) flour batter, along with a few spices in the batter, so works for all sorts of "can't haves.")
Anyway - I always see it as a personal challenge - and start working my way around the globe. Whatever you can't eat... there is a cuisine that never had it in the first place. Just strap on you shoes and start walking.
