Oven Roasted Sweet Potatoes

4 large sweet potatoes
1 c. melted "I Can't Believe It's Not Butter" (or butter/margarine)
1/4 c. red pepper flakes
1/4 - 1/2 tsp. garlic powder
2 Tblsp. minced garlic

Preheat oven to 350* Line a large cookie sheet with enough foil to hang over sides. Set aside.
Peel sweet potatoes and slice into thin rounds. (You don't want them paper thin, but not too thick either.) Place peeled & sliced potatoes into a large mixing bowl. Pour melted butter over potatoes and toss to coat. Spread potatoes and melted butter out onto lined cookie sheet. Arrange into one layer. Sprinkle remaining seasonings over top. Toss lightly to coat. Fold foil up around potatoes to form an "envelope." Bake for 60-75 minutes or until potatoes are fork tender.
