Heat oven to 375°F. Using sharp knife, trim off 1 side of zucchini to form a straight edge. Starting at straight edge, cut zucchini lengthwise into eight thin strips (about 1/8 inch thick). Place zucchini strips in shallow dish filled with hot water about 3 minutes to soften; drain.

In large bowl, thoroughly combine spinach, sour cream, cream cheese, Parmesan cheese, bread crumbs, egg, basil and 1/3 cup French Fried Onions. Line bottom and side of 9-inch pie plate or quiche dish with zucchini strips, allowing 3 inches of each strip to hang over edge. Spoon spinach mixture evenly into pie plate. Fold zucchini strips over spinach mixture, tucking ends into center of mixture.

Cover pie plate with foil. Bake, covered, for 40 minutes or until zucchini is tender. Top center of pie with cheese and remaining onions. Bake 3 minutes until onions are golden.
