Grilled Sweet Potato Packets with Pecan Butter

Why I Love This Recipe
Here's a recipe a friend directed me to on the TOH Recipes board last year!! I love sweet potatoes. I was skeptical about this recipe. But holy cow!! It is marvelous!! I usually make it on the grill. But have also made it in the oven several times!!! Yummmmmmm
Ingredients You'll Need
4 sweet potatoes (about 8 ounces each), peeled and cut into 1/4-inch-thick slices
1 large sweet or Spanish onion, thinly sliced and separated into rings
3 tablespoons vegetable oil
1/3 cup butter or margarine, softened
2 tablespoons packed light brown sugar
1/4 teaspoon salt
1/4 teaspoon ground cinnamon
1/4 cup chopped pecans, toasted
Directions
Prepare barbecue grill for direct cooking.
Alternately place potato slices and onion rings on four 14×12-inch sheets of heavy-duty foil. Brush tops and sides with oil to prevent drying.
Double fold sides and ends of foil to seal packets. Place foil packets on grid. Grill packets, on covered grill, over medium coals 25 to 30 minutes or until potatoes are fork-tender.
Meanwhile, to prepare Pecan Butter, combine butter, sugar, salt and cinnamon in small bowl; mix well. Stir in pecans. Carefully open packets; top each with dollop of Pecan Butter.
