For a spin on meatloaf, here's an idea for your next camping trip that actually uses an onion as the meatloaf pot. To make things easier, prepare your favorite meatloaf mixture at home before you leave and pack it in your cooler. For the cooking vessel, find some nice large, round onions and cut them in half. Carve out all but about three layers of several onions and pack the ground beef mixture into one half and then place the "lid" back on. Use the other parts of the onion for your meat mixture. Then wrap them in foil and toss them on the hot coals, making sure you turn them to cook it evenly, about 15 minutes per side.
