So easy, anybody can make it. It's tasty each and every time. Every time. There's secret ingredients. This is the first one. Tell us about it. These are pepperocini peppers, they're beautiful. Work well in the slow cooker and they give the roast a very distinct flavor in all right so that's the first one. Ah, this is going back. This is going back old school. Way back. I love.
