CHECK. Cardboard box oven...though the ones I've made sit flat, unexposed to the wind. Most anything that can be baked in a home oven can be baked in a cardboard box oven. The coals sit on a metal tray and the top of the box has an oven thermometer (the stick kind) jabbed into the top so we can tell about how hot the inside is.
DIY this easy oven for when you are camping (or picnicing outside! Bake most anything with this oven, made using a cardboard box and other common household materials! It also comes in handy as a food warmer or ice box. http://www.ehow.com/how_4441173_make-camp-oven.html?utm_source=pinterest.com&utm_medium=referral&utm_content=freestyle&utm_campaign=fanpage&crlt.pid=camp.lfHmspew9DtS
