Step 1

Bring a large pot of heavily salted water to a boil. Meanwhile, place 1 cup mayonnaise, 1 cup sour cream, 1 (1-ounce) packet ranch dressing mix, 1/4 cup chopped fresh soft herbs, and 1/2 teaspoon black pepper in a medium bowl and whisk to combine. Cover and refrigerate.

Step 2

Cut 6 ounces bacon crosswise into 1/4-inch pieces. Place in a medium skillet and cook over medium heat until crisp, 12 to 15 minutes. Transfer to a paper towel-lined plate and let cool. Meanwhile, core and dice 2 medium tomatoes (about 2 cups). Place in a large bowl, season with 1/4 teaspoon kosher salt, and toss to combine.

Step 3

Add 12 ounces dried pasta to the boiling water and cook according to package directions for al dente, about 7 minutes. Meanwhile, cut 1 medium head broccoli into small bite-sized florets, about 3 cups (reserve the stalks for another use). In the final minute of cooking time, add the broccoli to the pasta water.

Step 4

Drain the pasta and broccoli. Rinse with cold water to stop the cooking, stirring until cool to the touch. Drain well, or spin in a salad spinner to remove as much water as possible.

Step 5

Prepare the following, adding each the bowl of tomatoes as it is completed: Thinly slice 2 medium radishes. Finely chop 2 medium scallions. Drain 1 (4-ounce) can sliced black olives. Peel and grate 3 medium carrots on the large holes of a box grater (about 1 cup). Grate 4 ounces sharp cheddar cheese on the large holes of the grater (about 1 1/2 cups), or measure out 4 ounces store-bought shredded (about 1 cup).

Step 6

Add the pasta and broccoli, and 1/4 cup sunflower seeds. Toss to combine. Pour the dressing over a salad and toss until combined. Garnish with more herbs if desired. Serve immediately or cover and refrigerate for a few hours.
