Random craving but trying to find a sandwich pop-up from last summer

It might be a long shot but I had a sandwich last summer at a patio pop-up near Main St, charcoal BBQ meat in a baguette, sauce was unreal.

I can’t remember the name (something with munchies) and it’s been driving me nuts.

Anyone know if that spot ever came back? I think it might’ve been at the Boxcar patio but not 100% sure.
