Preheat solar oven for twenty minutes. Seal with casserole cover, tin foil, or oven bag, during baking. If using tin foil, remember to create a small ditch around the inside of the casserole dish to keep moisture inside and help prevent boil-overs.
This pan was filled to capacity and took a little over 90 minutes in the solar oven at 300F. (7500 BTUs - FREE) When done, the Kielbasa will 'snap' when bitten into and the vegetables will be soft without being limp. Best yet, at the end of the cooking period, there'll be a small amount of delicious au jus in the bottom of the dish.
I used Arborio rice cooked with chicken stock as a base so that we could enjoy the juices, as well. Colorful, isn't it, and just right for a holiday party. Hope you'll give it a try and let me know what you think.
