Sounds good to me if you also don’t put regular onions in it. Might come out a bit too oniony if you did. I’ve used potato chips instead of breadcrumbs and it comes out good. Didn’t change much with just regular Lays, which is what I used, though. Funyuns sound like it would be super good.
I’d also probably not add more salt than the funyuns. Those things are salty AF and probably have enough seasoning on them to be mostly all you need. Just crack some pepper in there too.
