The earthiness of cumin and heat of green onions balance against the natural sweetness of the root veggies, which are steamed first, then grilled to give them those char marks we all love.
In pan or steamer basket, steam carrots until tender-crisp, 8 to 10 minutes. Rinse with cold water to stop the cooking process. Drain.
Get grill very hot. Add carrots and scallions to pan until grill marks form and vegetables are heated through, 2 to 3 minutes on each side. Cut scallions into 1-inch pieces.
