Lightened up with Greek yogurt, this hearty sandwich is one of the quickest, most tastiest meals you'll ever have!
To make the pesto, combine basil, garlic, pine nuts and Parmesan in the bowl of a food processor; season with salt and pepper, to taste. With the motor running, add olive oil in a slow stream until emulsified; set aside.
In a large bowl, combine chicken, 1/2 cup pesto, Greek yogurt, salt and pepper, to taste.
Serve sandwiches on baguette with arugula, tomatoes, mozzarella and chicken pesto mixture.
