We once went on a camping trip without packing any utensils. We did however have chopsticks. Flipping burger one a grill with only chopsticks is an art form. You have to wait for the precise moment when the burger is cooked enough to not fall apart when flipped via chopstick but not enought to burn. Also you need to avoid flames or your chopsticks catch on fire. On the plus side, no washing up. You just burn them.
