Step 1

Add all of the pesto ingredients (except for the oil) to a food processor. Blend until a paste starts to form. Scrape down the sides and with the motor running, add oil until your desired consistency is reached. Taste and adjust the seasonings as needed. Set aside.

Step 2

Bring a large pot of water to a boil. Add the tortellini and cook according to the package instructions. It should only take a couple minutes - be sure not to overcook them. Drain and rinse with cold water.

Step 3

To assemble, add the tortellini, arugula, tomatoes, shallot, and lemon juice to a large bowl. Add the pesto (to taste) and stir until combined - this makes a lot of pesto, so you can reserve some on the side if you don't want to use it all.

Step 4

Serve immediately, or chill in the fridge. Top with torn basil right before serving.
