Wikipedia
Spaghetti squash — or vegetable spaghetti — is a group of cultivars of Cucurbita pepo subsp. pepo. The fruit ranges from ivory to yellow/orange in color. The orange varieties have a higher carotene content. Its center contains many large seeds. Its flesh is bright yellow or orange. When raw, the flesh is solid and similar to other raw squash; when cooked, the flesh falls away from the fruit in ribbons or strands like spaghetti.
