Prepare pasta according to package directions. Prepare your veggies and blanch the broccoli. Take a medium saucepan/pot and fill with water, enough to cover the broccoli. Add salt and take it to a boil. Reduce the heat and lower the veggies into the water. Cook on medium heat for 3 minutes, remove the vegetables with kitchen tongs, and place them into ice-cold water. Once cooled drain and pat dry with a towel. Set aside.
Sauce. In a bowl, mix together mayonnaise, vinegar, lemon juice, sour cream, parmesan, salt, and pepper.
Once the pasta has been cooked and drained well, place it in a large bowl.
Pour in the dressing, add the veggies, and cheddar. Stir well.
Cover the bowl with plastic wrap and put in the fridge to chill for at least 2 hours.
Before serving, add crumbled bacon, stir and serve immediately! Enjoy!
