1In 8-inch skillet, cook beef over medium-high heat 5 to 7 minutes, stirring occasionally, until thoroughly cooked; drain. Stir in water and taco seasoning mix. Cook uncovered over medium heat 2 to 4 minutes, stirring occasionally, until most of liquid is absorbed. Set aside to cool.
2Heat oven to 375°F. Spray cookie sheets with cooking spray. In medium bowl, stir Bisquick mix and 1/2 cup of the taco sauce until soft dough forms. Place dough on surface generously sprinkled with Bisquick mix; gently roll in Bisquick mix to coat. Shape into a ball; knead 10 times.
3Roll dough into 13x10-inch rectangle. Spoon beef mixture over rectangle to within 1 inch of long sides. Starting with 13-inch side, roll up tightly; pinch edge to seal. Cut roll crosswise into 1/2-inch slices, using serrated knife. Place slices 1 inch apart on cookie sheets.
4Bake 8 to 10 minutes or until light golden brown. Serve warm with remaining 1 1/2 cups taco sauce.
