Heat oven to 375 degrees F. Brown ground beef in large skillet over medium-high heat until thoroughly cooked, stirring frequently and drain. Add chili beans, taco seasoning mix and water; mix well. Reduce heat to medium; simmer 10 minutes or until ground beef mixture is slightly thickened, stirring occasionally.

 

Meanwhile, spray outside bottom and sides of (8) 6-oz custard cups, lightly with nonstick cooking spray. Separate dough into 8 biscuits. Roll or pat each biscuit to form 4-1/2-inch round.  Place rounds over outside of sprayed cups; press to fit over bottom and part way down sides of cups. Place cups, upside down, in ungreased 15 x 10 x 1-inch baking pan. Bake at 375 degrees F for 14 to 16 minutes or until deep golden brown. Remove pan from oven.  

 

Carefully remove biscuit cups from custard cups. Place biscuit cups, right side up, in same baking pan. Spoon beef mixture evenly into each cup. Top with cheese blend. Return to oven; bake an additional 5 minutes or until cheese is melted. Top with lettuce, tomato, sour cream and salsa.
