Directions

1. Peel onions and cut 1/2 in. off tops and bottoms. Place onions in a large saucepan. Cover with boiling water. Cook until tender, about 20 minutes; drain.
2. Cool slightly. Carefully remove inside layers of onion, separating into eight individual shells (refrigerate remaining onion for another use). Drain on paper towels.
3. In a skillet, cook beef and sausage over medium heat until no longer pink; drain. Add spinach; cook and stir for 2 minutes. Remove from the heat; stir in the remaining ingredients. Spoon into the onion shells.
4. Place in a greased 13-in. x 9-in. x 2-in. baking pan. Bake, uncovered, at 350 degrees F for 15-20 minutes or until heated through and lightly browned.
