Sweet Potato-Carrot Tsimmes

Bring 12 cups of salted water to a boil in a large pot.

Add the diced sweet potatoes and carrots to the boiling water, then reduce heat and simmer until both vegetables are just tender, about 12-15 minutes.

Drain the vegetables thoroughly using a colander and return them to the pot.

Add the halved prunes, orange juice, brown sugar, and cinnamon to the pot with the cooked vegetables.

Stir in the butter or margarine until melted and evenly distributed throughout the mixture.

Gently fold in the pineapple chunks with their juice and the drained mandarin orange pieces, being careful not to break up the cooked vegetables.

Heat the mixture over low heat, stirring occasionally, until warmed through and the flavors have melded together, about 8-10 minutes.

Transfer to a serving dish and serve warm as a vegetable side dish.
