Ideas for leftover roast pork tenderloin?

Banh Mi

I typically thinly sliced leftover pork tenderloin and add it to cuban sandwiches with ham, cheese, pickles, and mustard.

I agree with smslaw, I almost always use leftover pork tenderloin in a curry for a quick dinner

A few nights ago, we used leftover pork tenderloin in an Indian curry with mango. I think part of the trick is to not overcook the pork in the first place and then add it at the end of the curry cooking, just enough to warm it up.

Shred it (or use it thin-sliced) for a pork sandwich. Here's one good recipe. Just skip the part for cooking the pork and start instead at the section that begins "The sauce, slaw and putting your sandwich together."

There's a sandwich recipe on here called Caramelized pork banh mi that is great. Since a slice is kind of slider sized you could get some slider buns and grill or roast slices of peach, mango or pineapple and make sliders with a 1/2" slice of pork and a drop of hoisin, teriyaki or bbq sauce.

Well, a sandwich comes to mind. Also a burrito or a taco (both of which are, in a way a sandwich). You could also shred up the meat and work that into a tomato based sauce for pasta. It sort of depends on how you seasoned the pork in the first place.
