I have had it for 1 yr and have not explored all its uses, but I have used the Sun Oven primarily to cook foods that heat up a kitchen during the summer and autumn. I particularly liked cooking a variety of beans, all at once, in separate little pots for seasoned black beans (used as an ingredient in Latin foods), barbecue white beans to serve with grilled meats, and soupy, spicy, pinto bean soup. I would cook once a week in it and be done with the one ingredient that heats up my kitchen. I also used the oven for pasta dishes that required baking.
