I found the recipe at Allrecipes.com and it is called Sweet Potato Cranberry Bake. I used pecans instead of the walnuts because that's what I had on hand and I had some canned crushed pineapple in the refrigerator left over from a cake I baked last week so I used that instead of the orange juice. I also cooked my sweet potatoes in the microwave instead of boiling them.
I could eat this all day long! I love it. Hope you enjoy.
