Nacho B: Everything needed to make the griddled mortadella can be bought at Pastaworks on Hawthorne if you ever wanted to try and make one at home. mortadella, provalone piccante, mama lil's, a nice ciabatta roll or otherwise, and then however you want to dress it. It's a super-easy sandwich with a big pay-off, for sure. (This isn't to say that buying one from Lardo isn't great, also.)
¡Qué buena idea!
You're absolutely right. Other than their proprietary mustard blend (which I can't quite pin down exactly), I could easily replicate that sandwich at home with one trip to Pastaworks. As an aside, Pastaworks also stocks jamón para los bocadillos if you're missing an authentic taste of Spain. Going the DIY route might not save me much money in the long run, but (once the ingredients are in my possession) I won't have to worry about inconsistent cart hours and the shouting of names.
There is a danger to stocking Mama Lil's peppers and provolone piccante at home. I could easily break my weekly food budget as I'd be likely to start incorporating those ingredients into almost everything I prepare. We'll see about that, but I think it's a risk worth taking.
