Here's the response from Bad Wolf BBQ:
Thank you for your interest in Bad Wolf BBQ; we hope to see you at the Toronto Ribfest!
There are no peanuts of other nut products used in our ribs, bbq sauce, chicken coleslaw or beans. Our cornbread, however, while not containing nuts itself was nevertheless made in a facility which uses nuts in other products.
I hope this is sufficient information for your requirements.
Based on that response, I would feel fairly comfortable letting DJ try food - except for the cornbread - from the Bad Wolf BBQ stand.
And again - a shout out to any company that actually gets back to me.
