Chicken Salad w/ Blue Cheese and Grapes

This is an amazing summer dish!  Seriously, the most time consuming part is cooking the chicken (and I shredded it).

Ingredients
2 small heads Boston or Bibb lettuce, torn into pieces
4 stalks celery, sliced on the diagonal
1/2 red onion, finely chopped
2 cups (about 1/2 pound) green grapes, halved
3 ounces blue cheese, crumbled
2 tablespoons fresh lemon juice
2 tablespoons white wine vinegar
1/3 cup extra-virgin olive oil
kosher salt and pepper
1 3 1/2- to 4-pound rotisserie chicken, meat thickly sliced

Directions
In a large bowl, combine the lettuce, celery, onion, grapes, and blue cheese.
In a small bowl, whisk together the lemon juice, vinegar, oil, ½ teaspoon salt, and ¼ teaspoon pepper.
Divide the salad and chicken among plates. Serve with the vinaigrette.

I definitely didn't go hardcore, I just put lettuce in bowls and spooned everything on top.  Super simple, a nice light summer dish!
