Prepare tortellini according to package instructions.
Cut tomatoes in half; slice green onions; remove corn from cob; chiffonade basil.
Place sliced tomatoes, corn, sliced green onions and basil in a large bowl.
Place lemons on the counter. Press down on each lemon with the palm of your hand and roll the lemons back and forth several times. Zest one of the lemons before cutting in half to squeeze out the juice.
Shred parmesan cheese; zest lemon; squeeze lemon juice (over a mesh strainer to catch the seeds); mince garlic.
Add ½ cup parmesan cheese, zest of 1 lemon, 3 tablespoons lemon juice, 2 cloves garlic, ½ teaspoon salt, and ½ teaspoon pepper to the food processor bowl.
Process until smooth.
While food processor is running, add ¼ cup olive oil in a steady stream.
Add cooked tortellini and olive oil mixture to the large bowl with the tomatoes.
Mix well to combine.
Enjoy!
