Tonight, I am going to break into that Rojo Seasoning of Penzeys. I am so excited. I am going to use a pork tenderloin. While the Rojo is righteous all on its own I recommend a lime sour cream sauce (and frankly corn not flour tortillas). Below is the recipe for the lime sour cream.
1 c sour cream
1 c. mayo (did I mention this was not a low calorie sauce)
1 TBS lime juice
1 TBS lime zest
Mix and chill.
