Heat oven to 400°F. In 10-inch skillet, cook beef, onion, salt and pepper over medium-high heat 5 to 7 minutes, stirring frequently, until beef is thoroughly cooked; drain.
Stir in soup, peas and water. Heat to boiling, about 3 minutes. Reduce heat to low; simmer 5 minutes, stirring occasionally.
Meanwhile, separate dough into 10 biscuits. Wrap biscuit around each cheese cube, pinching edges to seal.
Place beef mixture in ungreased 1 1/2-quart round casserole. Arrange cheese-filled biscuits, seam side down, in single layer over hot mixture.
Bake 13 to 18 minutes or until biscuits are golden brown.
