Linguini with Leeks, Shrimp, and Arugula

1 (16-oz) bag linguini (or another long pasta), cooked and drained
1 Tbsp olive oil
1 Tbsp butter
2 leeks, cleaned and thinly sliced
1 tsp minced garlic
1/2 cup vegetable broth
1/2 pound medium shrimp, peeled and deveined
a handful of arugula
1/4 cup freshly grated Parmesan cheese
salt and pepper

In a medium saute pan, heat the olive oil and butter. Saute the leeks over medium-high heat until tender, about 5 minutes. Add the garlic and saute 1 to 2 minutes, until fragrant. Add the vegetable broth and bring to a boil. Reduce heat and simmer 5 minutes, until the sauce is slightly reduced. Add the shrimp and cook 3 to 4 minutes, until pink. Toss the leek-shrimp mixture with the cooked pasta. Add the arugula and toss. Add the grated Parmesan, toss, and adjust seasonings to taste with salt and pepper.
