Cook the bacon.
Bake or cook the bacon until crisp, then let it cool and chop it into bite-size pieces. The source specifically recommends baking it in the oven for an easier, less messy method.
Whisk the dressing.
In a large bowl, whisk together the Miracle Whip or mayonnaise, lemon zest, lemon juice, white wine vinegar, sugar, salt, pepper, dry mustard, and cayenne until smooth.
Chop the broccoli small.
Cut the florets into smaller pieces so the salad is easier to eat and every bite gets a little bit of everything. If you want, finely chop the broccoli stems and add those too.
Add the mix-ins.
Stir the broccoli, cranberries, sunflower seeds, cheddar, red onion, and most of the bacon into the bowl with the dressing. Hold back a little bacon for topping if you want a prettier finish.
Toss well.
Mix until the dressing coats all the ingredients evenly.
Serve chilled or at room temperature.
You can serve the salad right away, let it chill first, or bring it out after about 20 minutes on the counter if it has been refrigerated.
