First of all...... I want to live near you!! I've never been to a real "crop" with others. I'm tired of scrapping alone!!!
Anyhow.... how about a salad bar idea.... a large bowl of mixed greens and lots of smaller bowls of salad toppings. Be sure to include protein items, such as cheese cubes, pepperoni slice, bean salad, bacon bits, hard boiled eggs, as many people don't care for the idea of "veggies only" for dinner. If you wanted to give your CM a "month off" from the food responsibility, you could do it as a "pot luck" salad bar!
To elaborate on the crockpot idea, you could do fondue in crockpots..... cheese fondue for dinner and chocolate fondue for dessert!!.......Hope this helps..................P
