Great to hear.
Did this with our housewarming. Specifically said, "please no gifts, but do bring a favorite side dish, dessert or drink."
We had 5 different Mac n Cheeses.
Anticipating a successful potluck, I only made baked chicken legs, dusted off my grandmother's liquor cabinet (apparently, she hasn't had a drink since the Clinton Administration), and might have bought dessert, too, but don't entirely remember.
