When i was young there was a movie that i watched a ton, but now that i am older i can not remember the name. The movie came out sometime between 1980-to early 1990's.
Here is what i remember.
The movie started with a grandfather telling a story to the main character a small boy who would be moving to a new house with his family, on the trip to there new house they see a hitchhiker and pull over but before he could make it to the car they pull away. When they arrive at there house the town starts bringing them strange food always green ( Green jello Green cake/ pie w.e) and when the family eats it they turn into some sort of green goo that the town/ monsters eat. I dont remember much else other than the people were monster like and ran by some woman who ran a church.

IF Anyone remembers this movie PLEASE PLEASE help me out, i have been troubled by this for years.
