We took our Solar Oven to the craft show in mid October. Very early, about 8:30 am, I put lunch on to cook. I took the easy way out. I used a frozen Crock Pot meal – pot roast and veggies. It comes with a sauce packet to make gravy. Just add water. It drew some curious looks from a few other vendors, but mostly no one even noticed my cooker sitting quietly behind the canopy. Around 1:00 p.m., I put some dinner rolls in a plastic bag, and put them into the cooker to warm up. At 1:30, we enjoyed a hot delicious lunch of pot roast, warm rolls, and fruit salad from the cooler.
