Place beef in a 12 inch nonstick skillet over high heat, cook, turning and breaking up the meat, until it is crumbled and brown.
Meanwhile, use a rolling pin to flatten each bisuit until it measures about 4 1/2 inches accross and is 1/4 inch thick. Place flattened bisuits on and ungreased baking sheet.
When meat is browned, stir in the taco seasoning mix and water. Remove skillet from the heat. Place 2 tablespoons of meat in the center of each biscuit. Leave any meat you have leftover in the skillet. fold the dough over the meat to form a turnover, and press down edges with the tines of a fork to seal.
Bake about 8 minutes.
Meanwhile, add the tomatoes with their juice and the salsa-cheese sauce to the skillet with the leftover meat. cook until heated through.
To serve place turnovers on individual plates and top with the sauce.
