Spaghetti with Creamy Spinach and Tarragon

I got some spinach from the organic farm share and I was tired of eating it as salad or in soup. So I decided to put it in a pasta dish.

Ingredients
* 1 bunch of spinach, chopped
* 3 scallions including green tops, chopped
* 1 1/2 teaspoons dried tarragon(or basil)
* 3/4 teaspoon salt
* 3/4 pound spaghetti
* 5 ounces cream cheese(low fat or fat free preferred), cut into cubes
* 2 tablespoons chopped fresh parsley
* 1/4 cup grated Parmesan cheese
* 1/2 teaspoon fresh-ground black pepper

Preparation
1. Remove any tough stems from the spinach. In a large frying pan, heat over moderately low heat, add the scallions and tarragon and cook for 2 minutes. Add the spinach and salt and stir until wilted. Simmer until the liquid evaporates from the spinach, about 5 minutes.

2. In a large pot of boiling, cook the spaghetti until just done, about 12 minutes. Reserve 1 cup of the pasta water. Drain the spaghetti and toss with 3/4 cup of the reserved pasta water, the spinach mixture, the cream cheese, parsley, Parmesan, and pepper. If the sauce seems too thick, add more of the reserved pasta water.
