Step 1Cut the chicken into pieces about 1 inch by 2 inches. Remove the crust from the bread and cut it into pieces about the same size. Place the bread in a bowl with 2 tablespoons of the olive oil and toss to coat.
Step 2Bruise 2 sage leaves and chop them. Combine the white wine, the remaining olive oil, sage, garlic, salt and pepper in a bowl. Add the chicken and marinate 30 minutes.
Step 3On an 8-inch-long bamboo or metal skewer, thread 2 pieces of chicken, a whole sage leaf, a piece of bread and a piece of sausage. Cook on the bottom shelf under the broiler for about 8 minutes or on the grill over a low charcoal fire for 15 to 20 minutes, until the sausage and chicken are cooked.
