In a 6- to 8-inch frying pan over medium heat, stir nuts until golden, about 6 minutes. Let cool.
Cut chicken into 1/4-inch-thick strips 2 to 3 inches long. Rinse pear and cut lengthwise into quarters. Trim core from each quarter and discard; thinly slice quarters lengthwise.
In a large bowl, mix vinegar, olive oil, and 1/2 teaspoon garlic salt. Add spinach, cranberries, green onions, almonds, chicken, and 3/4 of the pear slices. Mix gently to coat.
Spoon 1/4 of the salad onto each of 4 dinner plates. Top portions equally with remaining pear slices and sprinkle with cheese. Add garlic salt and pepper to taste. Serve with spice crisps.
