Chopped Romaine and Radicchio Salad
1/4 cup freshly grated Parmesan
3 tablespoons extra-virgin olive oil  
2 tablespoons whole-grain mustard  
1 tablespoon Champagne vinegar  
1/4 teaspoon kosher salt  
2 hearts romaine lettuce  
1 large head radicchio
1/4 cup chopped fresh basil  
1/2 English cucumber, peeled and diced  
1 avocado, pitted, flesh scooped and diced  
2 cups pita chips, crushed  
1/4 teaspoon salt  
Instructions:
To a jar with a tight-fitting lid, add the Parmesan, olive oil, mustard, vinegar and salt. Screw on the top and shake vigorously to emulsify. Set aside to let the flavors marry.
In a large bowl, toss together the romaine, radicchio, basil, cucumber, avocado and pita chips. Pour the dressing over the salad, sprinkle with the salt and toss gently to coat and combine.
