Preheat an oven to 400°F. In a large skillet, warm oil over medium heat. Add the spinach and toss until wilted, about 4 minutes. Season to taste with salt. Remove spinach to cutting board and chop. Allow to cool.
In a medium bowl, mix the cheeses, dressing and cooked spinach until well combined.
Unroll crescent roll dough and separate into four rectangles. Firmly press perforations to seal the dough. Spread the spinach mixture evenly over the four rectangles.
Starting with the short side, roll up each rectangle. With serrated knife, cut each roll into six slices and arrange cut side down onto a parchment-lined cookie sheet. Bake for 15 minutes or until golden brown. Serve warm with extra dressing for dipping.
