Mine was reverse seared too. Forgot to say so in my OP.
Seasoned with coarse pepper, kosher salt and Lawry's, slow cooked at 250°F in the Outlaw pellet cooker until internal temp was 125°F, then seared over B & B lump charcoal on the PK300.
Should have seared it a little less (that's what happens when you try to cook and take pictures at the same time!) but it still tasted great in those tortilla shells and with the chimichurri.
