Step 1

Preheat oven to 400 degrees F.

Step 2

Combine meatballs and tomatoes on a sheet pan and drizzle with olive oil and season with pepper. (The meatballs will already be seasoned, so we’ll add more salt later if needed.)

Step 3

Roast until meatballs are heated through and tomatoes have burst, about 20 minutes. Most frozen meatballs are already cooked, so it’s really just getting them nice and hot that’s important. Toss meatballs and tomatoes with arugula, unless you’re serving it on the side.

Step 4

Meanwhile, cook orzo according to package instructions. Drain orzo, stir in butter to coat orzo and sprinkle with Parmesan cheese.

Step 5

Serve meatballs and tomatoes over orzo. Top with grated Parmesan cheese, red pepper flakes, and salt to taste.
