Ingredients

• 3/4 pound small red potatoes
• 1 pound carrots, cut into 1/4-inch-thick slices
• 1/2 pound green beans, trimmed and halved crosswise
• 1 large onion, sliced thin
• 2 teaspoons curry powder, or to taste
• 1 tablespoon vegetable oil
• 2 plum tomatoes, each cut into 6 wedges

Instructions

1. In a 4-quart saucepan bring 3 quarts salted water to a boil for vegetables. Cut potatoes into 1/4-inch-thick slices and boil until just tender, about 3 minutes. Transfer potatoes with a small strainer or slotted spoon to a bowl of ice and cold water to stop cooking. Cool potatoes and transfer with strainer or slotted spoon to a large serving bowl. Boil and cool carrots and green beans separately in same manner and add to potatoes.
2. In a large skillet cook onion and curry powder in oil over moderately high heat, stirring, until onion is softened and add tomatoes. Cook mixture, stirring occasionally, 1 minute and add to vegetables. Cool mixture.
3. In a small bowl whisk together mayonnaise and yogurt and stir into cool vegetable mixture with chicken, pork or ham, and salt and pepper to taste. Salad may be made 4 hours ahead and chilled, covered.
