Tortilla espanola? Spanish tortilla (egg/potato/onion). People love it.

sweet and sour meatballs.

both of these have been hits for me.

I'd love to hear responses as well. But my "potluck dish" will stay in the kitchen while the over-scheduled family comes in and out over a 4 hr time frame to eat dinner.

I need a dish that will hold up during travel for a potluck, it has to be good for all types of palates so not too exotic of a dish. Any ideas?
