Do you know if they own the house? Find out.
They could be renting the place or - as was the situation in my neighborhood - one of your bikers could have "borrowed" the house from a family member. In our neighborhood, the house previously belonged to a distant relative who passed away. The majority of the family lives over a thousand miles away, so they told their wastrel daughter that she could use the house while she was getting clean.
Needless to say, the "getting clean" process never happened. She invited a host of random people to hang out at her place and they trashed it over the course of almost a year. Eventually, the family found out about the situation when one of the neighbors thought to look into ownership. They kicked the daughter out of the house and have been gutting it for the last two months, trying to clear out all of the damage done by the daughter and her friends.
Long story short, find out who actually owns the house. That may give you some options...
I've gotten into polenta recently. I cook it up ahead of time and put it in a sealed dish in the fridge. When it cools and sets up, it's easy to slice into sections and eat as finger food. I can eat it plain, with hot sauce or sometimes I'll saute up vegetables (peppers, onions, zucchini, whatever) and add them to the polenta before it cools. The particularly cool thing is that I can eat it hot or cold. Once it's set up, it toasts up nicely too.
