Preparation To cook the chicken, bring a saucepan of water to a boil over high heat. Add the chicken and simmer for 15 minutes, or until cooked through. Remove from water and cool completely. When cool, cut into 1/2-inch/1.3-centimeter dice. Place in a bowl with the grapes, walnuts, dill, scallions, yogurt, salt and black pepper. Stir to combine. To assemble the sandwiches, place 4 slices of bread on a work surface. For each sandwich, top with 1/2 cup/10 grams arugula, 1/2 cup/70 grams chicken salad, 1/4 cup/29 grams sliced radishes and another piece of bread. You can also try substituting shrimp for the chicken and hazelnuts for the walnuts! Tina's Tip:Save the cooking water from the chicken. It will be lightly flavored from the chicken and can make a nice base broth for soup. Freeze it!Per Sandwich: Calories 260, protein 23 g, total fat 6 g, carbohydrates 28 g, sodium 460 mg, fiber 5 g Nutritional analysis provided by The Truly Healthy Family Cookbook Reprinted with permission from The Truly Healthy Family Cookbook: Mega-nutritious Meals that are Inspired, Delicious and Fad-free by Tina Ruggiero, M.S., R.D., photography by Bill Bettencourt.
