I like things a little bit spicy. The mild giardiniera adds to the flavor of the sandwich and doesn't burn. Chicago-style is packed in vegetable oil and doesn't taste all vinegary like other giardiniera I ate years ago. I think it's pickled in vinegar, drained, then packed in oil. And it's not enough oil to bother me.
I'm an omnivore, like a coyote or a bear, and will eat just about anything animal or vegetable. I'm eating a meat-free meal right now -- apple fritters.
I might have a sandwich later, and will eat some jerky or something if I don't.
Here's what that Texas Pete Hotter Sauce and Sweet Baby Ray's look like mixed together. The SBR's isn't so bright red anymore, and it tastes good after I shook it all together for a minute. It was way too vinegary and not hot enough before, and if I'm saying it's not hot enough it really wasn't hot, because I don't like things very hot. The mild and hotter sauces together are really good and I ate some more chicken with it for breakfast.
