You surprise me all the time. I've never seen purple potatoes. In my garden growing potatoes in the purple rind, but inside it is white!!!
Honestly, I hate semi-finished products or frozen pizzas. Although when I was young (haha, just kidding, I'm still young), I thought that frozen pizza and cola from the jar is very cool! But now, I'd rather boil potatoes and quickly fry chicken fillets, than eat frozen food.

I want to try your recipe!
