Cook in two separate pots in a solar oven, if your oven only has enough room for one pot, prep separately and then combine ingredients and cook in one pot.
Combine quartered potatoes, sausage, seasonings and oil into cooking pot, and mix. *this is lightly seasoned, if you prefer heavy seasoning, add more salt, pepper, and cayenne.
Combine brussels sprouts, onion, vinegar and seasoning in cooking pot
Position solar oven in a safe and sunny spot. Place potato and brussels sprouts cooking pot in oven, and place lids on pots. Seal oven (if applicable) and begin cooking.
Leave in sun for 3-4 hours (based on intensity of light). Carefully check to ensure food is thoroughly cooked by poking the biggest potato with a fork. If the blades of the fork easily slide through potato, the food is ready. If the potato is tough and difficult to puncture, continue cooking.
When food is ready, dish onto plates or serving dishes and enjoy! Remember to always be careful when opening and closing the solar oven, as temperatures inside will be hot, just like a conventional oven.
If you only have enough room for one pot inside your solar oven, prep ingredients (as explained in instructions) and then combine into ONE pot for the cooking process.
