Polenta Tamale Pie Tacos

We had quite a bit of the Polenta Tamale Pie left from last night, so with a few basic ingredients (taco shells, carrots, tomatoes, & lettuce) I made tacos. As my husband says, "You've got one here." The PTP tasted best the next day. I had to snicker a little - it reminds me of sourdough...you know how you're supposed to keep some of the old each time you make more? Well, with this, it's the black beans. First I made the black bean soup, then I used some of the soup to make the Polenta Tamale Pie, and then used some of the PTP in the tacos. How's that for using left-overs?! I love the saying "Waste Not, Want Not."
