Broccoli and Cauliflower Salad

1 bunch broccoli
a bunch of carrots
1 head cauliflower
1 Tbsp. onion flakes
1lb. Bacon, cut and fried (I just throw in a handful of crumbled bacon you buy for salads)
1 pkg. Snyders bbq or honey mustard pretzels (I think they've discontinued the BBQ ones)
Chop broccoli, Cauliflower, and Carrots into bite sized pieces. Add bacon and onions. Make dressing and add to vegetables.
Dressing
1 1/2 cups mayonnaise (I usually use only one cup)
1/4 cup parmesan cheese
1/3 cup sugar (I usually use 1/4 cup)
Blend it all together and pour on the veggies. Let it sit for a few hours. Just before serving, add the pretzels.
