Step 1

Preheat oven to 350F.

Step 2

Cook the pasta shells according to packet instructions so they are al dente. Drain and set aside on a baking sheet.

Step 3

Meanwhile, warm the oil in a medium skillet over a medium heat. Add the garlic and cook a minute or two until fragrant. Next add the pork and cook a minute to soften. Add the arugula and cook, folding it in so it all wilts down. Set aside to cool a minute.

Step 4

Mix together 1/2 of the mozzarella (ie 1/4 cup) with the ricotta, add the pork mixture and mix.

Step 5

Put approximately 1 1/4 cups of the marinara sauce in the bottom of a baking dish.

Step 6

Fill the pasta shells with the pork-cheese mixture and set in the marinara in rows. (You might not use quite all of them, but a couple often break in boiling.)

Step 7

Top with the remaining marinara sauce, the rest of the mozzarella and the parmesan.

Step 8

Cover and bake for 30-40 minutes, uncovering for the last 5-10 minutes.
