Strawberries in Yogurt Sauce

1 cup plain non-fat yogurt
2 Tablespoons firmly packed brown sugar
1/2 (one-half) teaspoon ground cinnamon
1 teaspoon vanilla extract

In a small bowl, whisk sauce ingredients until fully mixed. Refrigerate one hour to firm. Divide berries evenly into four dessert dishes. Spoon one-quarter cup sauce over each serving and serve immediately.
