Heat oven to 400˚F.
Coat pumpkin with a few tablespoons EVOO, season with salt, pepper and nutmeg and roast 15 minutes. Turn squash over and roast 15 minutes more.
When pumpkin is a few minutes away from being done, bring a large pot of water to a boil for ravioli.
Heat a drizzle of EVOO in a large skillet over medium heat. Add pancetta and crisp, 4-5 minutes. Remove with a slotted spoon and wipe the fat drippings out of the pan.
Drop ravioli in the boiling water and cook 3-4 minutes.
While the ravioli cook, melt butter in the skillet then add sage leaves and crisp them up, about 2 minutes. Carefully remove leaves, reserving them on a plate. Reduce heat under skillet a bit and allow the solids in the butter to brown.
