Begin by cooking the spaghetti in a large pot of boiling water according to the package directions.

Drain the cooked pasta, but remember to reserve 1 cup of the pasta water.

In a large skillet over medium heat, warm the olive oil, then sauté the shallots and garlic for about 1 minute.

Add the French green beans to the skillet and cook until they are tender yet still crisp, approximately 3 to 4 minutes.

Toss the drained spaghetti into the skillet with the green beans mixture. If desired, add some of the reserved pasta water to create a sauce-like consistency.

Finish the dish by topping it with freshly chopped basil, parsley, mint, cilantro, a squeeze of lemon juice, and chopped toasted walnuts.
