Multicooker Directions: In Step 1, remove the lid of a 6-quart multicooker. Place the oil in the inner pot. Press SAUTÉ [Normal], and heat, swirling to coat the bottom of the pot. Add the onions and celery, and cook uncovered, stirring often, until the vegetables are just tender, about 6 minutes. Turn off the cooker. In Step 2, add the chopped tomatoes, mushrooms, tomato paste, strained tomatoes, wine, zucchini, garlic, oregano, and salt to the pot; stir well. Lock the lid; turn Pressure Valve to "Venting." Cook on SLOW COOK [Normal] until the mixture has thickened, about 5 hours and 30 minutes. Finish Step 2.
