i'm skeptical...you're adding an additional cooking step (re-warming) plus freezing for however long... sounds like a recipe for breaking down the extra nutrional value, extra fiber, and superior taste, which is the whole reason to bother with steel cut. of course, you could just try it, and see what happens. i'm pretty sure that they would keep pretty much indefinitely (at least 6 months, preceeding statements about lost nutritional value notwithstanding)
