In a small bowl, combine pears, cranberries, orange juice or water, the 2 teaspoons finely chopped crystallized ginger, the cinnamon, and vanilla. Divide mixture between two 8- to 10-ounce individual baking dishes.
In another small bowl, stir together oats, brown sugar, and flour. Stir in melted butter. Sprinkle oat mixture and almonds over pear mixture in baking dishes.
Bake for 20 to 25 minutes or until pears are tender and almonds are golden brown. Serve warm. If desired, top with yogurt and additional crystallized ginger.
