Ingredients
1 1/2 pounds frozen beef tortellini (from two 1-pound bags)
1/2 cup sun-dried tomatoes, thinly sliced
Coarse salt and ground pepper
2 bunches arugula (12 ounces total), washed well and torn into large pieces
2 tablespoons butter
Preparation
Cook pasta and tomatoes in a large pot of boiling salted water until al dente, according to package instructions. Reserve 1/2 cup pasta water. Drain pasta mixture, and return to pot.
Add arugula and butter to pasta. Toss, adding reserved pasta water a little at a time to create a thin sauce that coats tortellini (you may not need all the water). Season with salt and pepper; toss to combine. Serve.
