Philly Beef Squares

1 1/2 teaspoons dried minced onion
1 lb lean (at least 80%) ground beef
3/4 cup cheese dip (from 15-oz jar)
2 cups Original Bisquick® mix
1 cup milk
1 egg
2 cups frozen bell pepper and onion stir-fry (from 1-lb bag), thawed, drained

Heat oven to 375°F. Spray 8-inch square pan or 2-quart glass baking dish with cooking spray. In small bowl, cover onion with hot water.
In 10-inch skillet, cook beef over medium-high heat 5 to 7 minutes, stirring occasionally, until brown; drain. Stir in cheese dip. Cook 2 to 3 minutes or until hot.
In medium bowl, mix Bisquick mix, milk and egg until blended. Pour half of the batter into pan. Top with beef mixture and bell pepper mixture. Pour remaining batter evenly over top. Drain onion; sprinkle over batter.
Bake 40 to 45 minutes or until golden brown and center is set. Let stand 5 minutes before cutting into squares. If desired, heat leftover cheese dip as directed on jar and spoon over each serving.
