I found this recipe on Eating Well’s website, but couldn’t find Watercress and wanted to adapt the recipe a bit.  Here it is!

Ingredients:

• 2 pounds Russet potatoes
• 1 1/2 cups flour
• 1 teaspoon salt
• 1 large egg, lightly beaten

• 2 ounces pancetta, chopped
• 3 cloves garlic, minced
• 2-3 large tomatoes, chopped
• 1/2 teaspoon sugar
• 1/4 teaspoon crushed red pepper
• 2 teaspoons red-wine vinegar
• 1/4 teaspoon salt
• 1 bunch of spinach (4-5 cups), cleaned and stems removed
• 1/4 cup freshly grated Parmesan cheese

Directions:

Preheat oven to 400 degrees.

For the Gnocchi:  Prick potatoes all over with a fork.  Bake the potatoes in the oven for 45 minutes to 1 hour until they are fork tender.  Remove from oven and cool slightly.  Alternatively, cook potatoes in microwave until fork tender. Peel the potatoes. Grate potatoes on a box grater or push through a food mill.  DO NOT MASH (it breaks down the structure and releases the water from the potatoes, so the gnocchi do not turn out right).

Gently combine the potatoes with the lightly beaten egg and salt.  Gradually begin to add the flour, a quarter cup at a time, until the dough is not sticky.  Avoid over-mixing, again this will ruin the consistency of the gnocchi and they could come out chewy.  Put dough on lightly floured surface and need 3 to 4 times.  Divide dough into six parts, rolling each part into a rope.  Cut rope into desired gnocchi size (usually about 1/2-3/4 inch thickness).  Set aside.  You can add ridges to the gnocchi if you want, but I never do.

For the sauce:  Bring a large pot of water to boil.  Add salt to the boiling water.  Cook pancetta in a large nonstick skillet over medium heat, stirring occasionally, until it begins to brown, 4 to 5 minutes. Add garlic and cook until golden brown. Add tomatoes, sugar and crushed red pepper and cook, stirring, until the tomatoes are almost completely broken down, about 5 minutes. Stir in vinegar and salt. Remove from the heat.

Cook gnocchi in the boiling water until they float, 3 to 5 minutes. Place spinach in a colander and drain the gnocchi over the spinach.  This will wilt the spinach just enough for the pasta. Add the gnocchi and spinach to the sauce in the pan; toss to combine. Top with Parmesan.
