Cranberry Streusel Sweet Potatoes

Here's something else we like to make with a big can of sweet potatoes.  This one's somewhat healthier than the previous recipe.

Cranberry Streusel Sweet Potatoes

1 (2 1/2 lb.) can Sweet potatoes -- drained
4 tbsp. Butter -- melted, divided
1/2 tsp. Salt
1 slice White bread -- cubed
1/4 cup Craisins
1/4 cup Pecans -- chopped

Mash sweet potatoes with salt and 2 tbsp. butter. Spread into a 1 quart casserole. Mix remaining ingredients. Sprinkle over sweet potatoes. Bake, uncovered, for 30 minutes.
