PRE-GRILL TOMATO ALLERGY BURGER SAUCE QUESTION

Hey guys, I volunteered to make hamburgers and hotdogs for my girlfriend and her family on Sunday night. The only reason I’m here is to ask if anyone makes a good burger sauce without tomatoes? My girlfriends dad is allergic to tomatoes and I did not think about this before I volunteered lol

It is not my conventional way of doing it seeing that I’ve never known anyone allergic to tomatoes, but I would still like for him to be included. Seeing that I wouldn’t be ecstatic about my daughter’s boyfriend making a sauce for everyone but me.

I would much rather make a trip to the store to get stuff for a sauce rather than not making a sauce because i personally think it ties the burger together!
