Freshly made or store-bought, carrot juice is packed with beta-carotene, iron, and potassium and adds health benefits and sweetness to this salad dressing.
In a small skillet, bring juice to a boil. Reduce heat; simmer until reduced by half, about 5 minutes. Pour into a large bowl. Whisk in lemon juice, oil, and cumin; season with salt and pepper. Add lettuce and onion; toss to coat. Serve, sprinkled with pumpkin seeds.
To make pumpkin seeds, heat a small skillet over medium heat. Add pumpkin seeds; cook, tossing until puffed and golden brown, 1 to 2 minutes. Makes 1/3 cup.
