My mom and I stumbled upon this concoction on the day after Christmas. I had received a french fry cutter ($20 at Bed Bath & Beyond), and we were experimenting with it. Before long, we figured out how to make little cubed potatoes, and then started cubing every veggie we had in the fridge. When we were done, we had a huge plate of cubed food and we felt bad throwing it all out. So we made the obvious decision - fry it all up in butter!
It ended up tasting amazing, and I made it again to bring to a New Years Eve dinner party the next week. It received rave reviews!
