bland or unhealthy food that is particularly nondescript or unappetizing. Undesirable food. A weird stew.
My friend cooked me dinner... and while she's always talking about exotic cuisine, all she made was a crummy plate of grelch.
The refrigerator is full of grelch - there's nothing to eat.
I don't know what the soup of the day is... it looks like grelch.
The frozen turkey pot pie looked good on the box, but it tasted like a grelch pie.
