Meals ideas for large groups?

I always like the ease of a large cut of meat like pork butt (hey, I'm southern--when is barbecue not a good idea for a party?). Of course, you have to cook it a long time, but there's really not that much fuss involved, and with a couple simple sides like a big salad or slaw, you're good to go. Leftovers also happen to be fabulous.

These ideas all sound yummy! Thanks for the help...

Black bean soup with garnishes like avacado, cilantro, shredded cheese, avacado and tortilla chips.

I would definitely not have meat or fish at room temperature for a couple of hours. A kale salad would be good

Both these dishes would compliment Sam's recommendation.

vegan, gluten free, and keeps very well...serve at room temp, and is better if made the night before serving. Just be sure to cover it well so the rice doesn't dry out. Save a bit of dressing to moisten it up in the morning.

lasagna works well.
