Green Bean Casserole

Make this easy green bean and mushroom casserole as a side for Thanksgiving to accompany the turkey :-)

Prayers of thanks and special thanksgiving ceremonies are common among almost all religions after harvests and at other times.
The Thanksgiving holiday’s history in North America is rooted in English traditions dating from the Protestant Reformation. It also has aspects of a harvest festival, even though the harvest in New England occurs well before the late-November date on which the modern Thanksgiving holiday is celebrated.
