Some of the campgrounds in Australia had microwaves. They do things differently there ... they don't have individual picnic tables and fire pits at each campsite, instead, they have camp kitchens equipped with stoves, fridges, sinks, sometimes microwaves, pots and pans, and a "room" (roof, cement floor, occasionally walls) full of tables. You label your food and put it in the fridge or cupboards ... there is often community salt and pepper, and butter.

I really like that idea!! You don't need to bring a stove or any cooking gear with you ... just maybe a cup, plate, and utensils ... and you can cook up a whole variety of stuff!
