I cut the Squash in half and removed the seeds. I baked the squash cut side down for 45 minutes. Meanwhile I sauteed chopped onion in a knob of butter. Added ground beef and browned it. After the meat cooled I mixed it with 2 eggs, 1 chopped tomato, 1/4 cup Parmesan Cheese and 1 cup Cheddar Cheese salt, pepper, parsley and oregano. Then I filled each squash half with the mixture and topped it with Panko Breadcrumbs and baked at 350 degrees for 20 minutes.
It was a snowy (?) night and this was a warm and comfortable meal.
