Bring a large pot of water to a boil, salt it, add the pasta and cook until al dente. Drain, reserving 1 cup of the pasta cooking water.
While the pasta is working, halve the zucchini lengthwise and scrape out the seeds. Thinly slice into 1/4-inch-by- 2-inch strips--think fat matchsticks.
In a large skillet, heat the EVOO, 3 turns of the pan, over medium-high heat. Stir in the chile and garlic for a minute. Add the zucchini, season with salt and pepper and cook until tender, 8 to 10 minutes.
Add the lime juice to the zucchini and stir in the butter to melt. Add the pasta, parsley, mint, tarragon (or basil), a handful of cheese and the reserved pasta cooking water. Toss for 1 to 2 minutes. Top with more cheese and the pistachios.
