Spam. People always seem to freak out over this stuff, but I just don't see why people get so up-in-arms about it. Then again, I'm also from Hawaii and it was in at least one meal a week.
Tripas and lengua. Mmm. Tripe and cow's tounge. Great in tacos. Chopped fine, thrown on a hot cooktop to warm through (or crispy up in the case of the tripe), slap em down on some corn tortillas, all a bit of chopped onions, cilantro, and some red sauce, and I'm in heaven.
