Here is that sweet-potato recipe I mentioned - I've not tried to make it but did eat it (warm) and enjoyed it. It's from a book called "Just Add Water," but the guy who made it, a local Orthodox deacon, found it on line at epicurious.com.

SWEET POTATO SALAD WITH CHILI-LIME DRESSING
Printer version of this recipe

This is a great summer salad, perfect with all kinds of barbecue and grilled foods. It's also a wonderful way to brighten up a winter dinner of broiled chicken or beef.

2 pounds sweet potatoes, peeled and cut into 1-inch chunks
1/3 cup extra-virgin olive oil
2 tablespoons fresh lime juice
1 teaspoon chili powder
1 /2 teaspoon ground cumin
1/4 cup finely chopped fresh cilantro leaves
salt and freshly ground black pepper to taste
1/2 medium-size red bell pepper, seeded and cut into 1/4 inch dice
4 scallions, white and light green parts, finely chopped

Place the sweet potatoes in a large saucepan and cover with water. Bring to a boil and cook until just tender, 7 to 10 minutes (don't overcook or your salad will be mushy and falling apart.) Drain and transfer to a large bowl.

While the potatoes are cooking, make the dressing. Whisk together the olive oil, lime juice, chili powder, cumin, cilantro, salt, and pepper in a small bowl. Add the red bell pepper and scallions to the potatoes and toss with the dressing. Season again with salt and pepper. Serve warm or refrigerate and bring to room temperature before serving.

Makes 6 servings.
