1. Wash broccoli and cut into florets. You can use fresh broccoli florets for this recipe or drop them into boiling water for about a minute and let cool.
2. In a large skillet, place bacon strips and fry them until golden brown. Drain on a paper towel-lined plate.
3. In a bowl, combine the broccoli, crumbled bacon, chopped onion and raisins. Add balsamic vinaigrette, mayonnaise, sugar, salt and toss to coat. Refrigerate until serving.
