Pour the spices into a spice grinder and grind to desired texture. You can feel the ground spices to see whether you need to grind more. The whole peppercorns will be the determining factor. You can feel the texture and determine if you’d like less.
In a 1-quart glass measuring cup (or bowl), combine the oil and vinegar. Add 3 tablespoons of the ground spice mix and the white pepper, and allow it to sit for 20 minutes. Taste and add another tablespoon of the ground spice until the desired flavor is reached. Set the dressing aside. (I use 4 tablespoons.)
Bring the water and salt up to a rolling bowl. Placing a lid on the pot will heat the water quicker.
Add the pasta and stir well. Bring the water back up to a boil and cook the pasta for 13 minutes or until al dente. Your timing may differ so taste the pasta (carefully) to check for doneness. Drain the pasta into a colander and rinse with cold water until the pasta is cool. Set aside.
While the water is coming up to a boil and then cooking, prepare the veggies. Multitasking helps with time management.
In a large bowl, combine the pasta, tomatoes, cucumber, onion, olives, peppers, broccoli, and green onions.
Stir the dressing once more, taste and adjust if desired. Pour over the pasta and veggies and toss well.
Serve immediately, or cover and chill for up to 4 hours. If you need to make this pasta days in advance, I highly suggest that you prep the veggies and dressing up to 3 days in advance; keep them separate from one another. Make the pasta the day you are serving. Bring the dressing to room temperature, then combine the pasta, vegetables, and dressing before serving. Add any sea salt as needed, to taste.
