Combine dry soup mix and water in small bowl. Microwave on high for 2 minutes. Spread refrigerated French bread loaf flat and cut in half lengthwise. With each half create a semi circle and place on lightly greased pizza stone.
Join edges together to create a circle.
Spoon spinach mixture onto the crust or the inside edge of the circle. Cut small vents in the crust to allow steam to escape. Top with SPAM Oven Roasted Turkey slices, followed by slices of Swiss cheese. Fold edges of crust over filling to seal. Bake in 350 F. oven for about 25 minutes until lightly brown.
