Heat oven to 350°F. Spray cookie sheet with cooking spray. Unroll dough and separate into 8 triangles; press out each triangle so shortest side measures 4 inches. Cut each triangle in half lengthwise from tip end to short side to make 16 triangles.
Brush each triangle with salad dressing. Top each with 1 cheese strip, scant 1/2 teaspoon roasted peppers and 2 pieces of beef, folding to fit on triangle. Roll up each, starting at shortest side of triangle and rolling to opposite point; place point side down on cookie sheet.
Bake 13 to 18 minutes or until golden brown. Immediately remove from cookie sheet. Serve warm.
