I did a slight variation on the recipe and used about twice as much chicken and a little bit more salad. The chicken came out great (2x the seasonings as well) and it was really good on top of the salad. A fairly healthy dinner where no sacrifice of taste was made..

Ingredients:
2 tablespoons olive oil, divided
2 (6 ounce) skinless, boneless chicken breast halves
1 1/2 tablespoons Cajun seasoning
2 cloves garlic, crushed
1 tablespoon balsamic vinegar
1 teaspoon Dijon mustard
salt and black pepper to taste
2 cups mixed salad greens
1 avocado – peeled, pitted, and diced

Warm 1 tablespoon olive oil in a large skillet over medium heat. Season both sides of chicken with Cajun seasoning, and place in hot oil. Stir in crushed garlic. Cook chicken 5 minutes on each side, or until juices run clear. Remove chicken from skillet, drain on paper towels, cool slightly, and dice; discard oil and garlic.

In a small bowl, mix remaining olive oil, balsamic vinegar, mustard, salt, and pepper.

In a large bowl, gently toss the dressing with the mixed salad greens, arugula, avocado, sun-dried tomatoes, and olives. Top with diced chicken to serve.
