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.
2 cups finely chopped radicchio (from 1/2 large head)
1/2 cup drained canned white beans, rinsed and patted dry
8 oil-packed sun-dried tomato halves, drained and chopped
Instruction:
Whisk the vinegar, 1/4 teaspoon of salt, and 1/8 teaspoon of pepper in a large bowl to blend. Gradually whisk in the oil to blend. Add the lettuce, radicchio, beans, and sun-dried tomatoes. Toss to coat. Season the salad, to taste, with more salt and pepper, and serve.
