1Heat oven to 375°F. Grease bottom and side of 1 1/2-quart round casserole with shortening. In 10-inch skillet, cook beef over medium heat, stirring occasionally, until brown; drain. Stir in beans, tomato sauce, brown sugar and onion. Pour into casserole; set aside.
2In medium bowl, stir remaining ingredients until soft dough forms; beat vigorously 20 strokes. On surface dusted with Bisquick mix, gently roll dough in Bisquick to coat. Shape dough into ball; knead about 10 times or until smooth. Pat ball into 7 1/2-inch round or round the size of top of casserole. Place on beef mixture in casserole.
3Bake uncovered 15 to 20 minutes or until crust is light brown.
