Preheat oven to 400. Prepare the delicata and acorn squashes. For the delicata (skin on!) cut off the top, and scoop out the seeds, and slice into rings. Place the rings on the baking sheet and add a little olive oil and salt. Cut your acorn squash in half, scoop out the seeds, and place alongside your delicata rings, dousing with olive oil. After 20 minutes, flip acorn squash over, remove the delicata from the sheet, and return the acorn squash only to the oven for another 20-25 minutes.
