Combine 2 tablespoons salt, the olive oil, and 4 quarts water in a large pot over high heat and bring to a boil. Add the rotini and cook, stirring occasionally to keep the pasta from sticking together, until just al dente, about 9 minutes.
Meanwhile, mash together the garlic and remaining 1/2 teaspoon salt in a large bowl. Add the balsamic vinegar, Italian Essence, black pepper, and crushed red pepper. Whisk to blend. Gradually whisk in the olive oil.
Drain the rotini and rinse under cold running water until cool. Add to the vinaigrette, along with the provolone, tomatoes, salami, prosciutto, parsley, and basil. Toss to mix. Serve immediately or cover and refrigerate until ready to serve. Let the salad return to room temperature before serving.
