Grilled Sweet Potatoes with Gremolata

Preheat grill to medium-high.

Combine mint, orange zest, sugar and salt in a small bowl; gently crush together with the back of a wooden spoon. Set aside.

If using small sweet potatoes, cut into 1-inch-thick wedges. Toss the sweet potatoes with oil and pepper in a medium bowl. Place in a single layer on the grill or in a grill basket. Cook, turning every 5 minutes, until tender when pierced with the tip of a knife, 20 to 25 minutes total.

Transfer the sweet potatoes to a large bowl. Add butter and toss to coat. Serve with the reserved orange-mint gremolata.
