1/2 pound bacon
4 heads broccoli, cut into bite-size pieces
1 1/2 cups raisins
1 1/2 cups unsalted sunflower seeds
1/2 cup chopped onion
1 cup mayonnaise
1/4 cup white sugar
1/4 cup granular sucralose sweetener (such as Splenda(R))
2 tablespoons white wine vinegar
Place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon slices on paper towels and crumble.
Toss bacon, broccoli, raisins, sunflower seeds, and onion together in a large bowl.
Whisk mayonnaise, sugar, sweetener, and vinegar in another bowl until smooth. Pour over broccoli mixture and toss to coat. Refrigerate until ready to serve.
