To prepare the squash, cut it in half and scrape out the seeds. Rub butter on the cut halves and place in a 350 degree, preheated oven. Cook about 45 minutes or until a fork easily slides into the squash. Let cool and scoop out of the shell. Add a pinch of salt and a few grinds of pepper and mash with a fork until nicely combined. Then follow The Martha's directions to create some tasty, tasty lasagna.
