1Heat oven to 450°F. In medium bowl, stir Bisquick mix, milk and cheese with fork until soft dough forms; beat 20 strokes. Place dough on surface generously dusted with Bisquick mix; gently roll in Bisquick mix to coat. Shape into a ball; knead 10 times. Roll 1/4 inch thick. Cut into 6 biscuits with 3-inch round cookie cutter.
2Place biscuits on ungreased cookie sheet. Bake 6 to 8 minutes or until golden brown.

In small bowl, stir remaining 1/3 cup water and the flour until mixed; stir into beef mixture. Heat to boiling, stirring frequently, until thickened.
