Place the cubed sweet potato and Delicata squash into a mixing bowl. Season with salt and pepper.
Coat the bottom of your a frying pan with oil.
Heat the pan up over medium high heat. When hot add the squash and sweet potato.
Cook until browned and cooked all the way through.
If you find that either two are completely browned but still not soft enough in the middle, then add a bit of water, reduce the heat and cook until soft in the middle. Then boil off all the water and crisp up the squash and sweet potato, being careful not to burn them.
