Yellow vegetable from a plant in the gourd family?

The most likely answer is squash.

There are many varieties of squash that come in a beautiful yellow color, including:

* Butternut squash: This is a popular choice with a sweet, nutty flavor.

* Acorn squash: Another sweet variety with a firm, dense texture.

* Yellow Crookneck squash: This is a long, curved squash with a mild flavor.

* Yellow zucchini: This is a smaller, more delicate squash with a mild flavor.
