Prepare pasta according to package directions. Chop broccoli, onion and bacon.
In a bowl, mix together mayonnaise, red wine vinegar, sugar, salt and pepper.
Once pasta has been cooked and drained well, put it in a large bowl.
Pour in mayonnaise mixture, chopped broccoli and diced onion (don’t add the bacon in yet, you want to add that in right before serving so it stays crunchy).
Cover bowl and put in the fridge to chill for at least 3 hours.
Before serving, add crumbled bacon to salad and then give it all a good stir and then serve.
Some additional add-ins that would be delicious in this are some halved red grapes (1 1/2 cups) and chopped pecans (1 cup). Before serving, add crumbled bacon to salad and then give it all a good stir and then serve.
