Step 1

Preheat oven to 400 degrees. Arrange prosciutto in a single layer on a parchment paper-lined rimmed baking sheet. Brush lightly with oil, and bake until crisp, about 10 minutes. Let cool completely.

Step 2

In a large pot of boiling, salted water, cook tortellini according to package instructions. Add peas, then immediately drain. Let cool 10 minutes, then toss in a large bowl with lemon zest and juice, and olive oil. Season with salt and pepper.

Step 3

Break prosciutto into large pieces and toss with pasta along with arugula. Serve in bowls topped with cheese.
