Bring a large saucepan of salted water to a boil. Add the green beans and cook until tender-crisp, 1 to 2 minutes. Drain and immediately transfer the beans to a bowl of ice water until cool. Drain the beans again and set aside.
Place the prosciutto in a large nonstick skillet set over medium-high heat. Cook until the prosciutto is starting to crisp, stirring occasionally, 4 to 5 minutes. Transfer to a piece of paper towel.
Heat 1 teaspoon olive oil in the skillet, then add the shallot. Cook, stirring occasionally, until the shallot is browned and tender, 2 to 3 minutes.
Add the green beans, remaining 1 teaspoon olive oil, pistachios, parsley, thyme and pepper to the shallots. Cook for about 1 minute to heat the green beans. Toss with the prosciutto. Serve.
Notes
Haricot verts are skinnier than standard green beans, so take less time to cook. If using thicker green beans, adjust the cooking time accordingly.Please note that I am not a medical or nutritional professional.
