Whisk together the first 5 ingredients in a large saucepan over medium-low heat; cook, whisking constantly, 6 to 8 minutes or until thickened (Note: pudding always takes me twice the time the recipe lists--usually 15 to 20 minutes.).

Let pudding stand 5 minutes, then gently stir in bananas.

Arrange 15 vanilla wafers in single layer on bottom of a 1 1/2 quart bakign dish. Sprinkle 1/2 cup pecans on wavers. Pour half of pudding on top. Repeat layers, ending with pecans.

Beat egg whites and 1/8 cream of tartar at high speed until foamy.

Add remaining sugar one teaspoon at a time, beating until soft peaks form (1 to 2 min).

Spread meringue evenly over top, sealing edges.

Bake at 400 degrees for 8 to 10 minutes or until golden brown.
