This is a great recipe. I use frozen, cubed sweet potatoes. I also use regular diced tomatoes and add a can of diced green peppers. I use concentrated orange juice in a little water so I don't need to keep OJ in the fridge. I didn't have scallions in the house and I don't add the lime juice and cilantro at the end. My houseguest and husband love this recipe. Sometimes I will add black beans to it. I also have served it over brown rice.
