To get started, you need a good thermos. Look for one that will retain heat for at least 5 hours. Pre-heating the thermos prior to adding ingredients is a very important first step. To pre-heat: place boiling water into thermos and let stand for 5-10 minutes.
In a saucepan warm the olive oil over medium high heat. Once the oil is fragrant, add all the vegetables and garlic, then sauté until tender.
Add all ingredients to the pre-heated Thermos and stir before replacing the lid. Allow to cook at least an hour. Will stay hot as long as indicated on Thermos label.
