In a small bowl, add all the marinade ingredients. Whisk to combine.
¼ cup olive oil, ¼ cup fresh lemon juice, 3 cloves garlic, 1 teaspoon dried oregano, ½ teaspoon salt, ½ teaspoon pepper
Add the diced chicken to the bowl. Toss to combine. Marinate for 30 minutes to 2 hours.
¼ cup chicken marinade, 2 large Chicken Breasts
Heat your grill or grill pan to medium-high. Cook the chicken for 3 to 5 minutes until done.
Honey Lime Dressing: While the chicken is cooking, whisk the dressing together. You can also do this ahead of time and refrigerate.
2 tablespoons lime juice, ¼ cup honey, ¼ cup olive oil, ⅔ cup Greek yogurt, ¼ cup fresh cilantro, 1 teaspoon dried oregano, salt and pepper to taste
Put it together: In a large bowl, add the chopped romaine, onion, bell pepper, avocado, and mango. Top with the cooked chicken. Top with the dressing.
1 large Lettuce, ½ medium Red Onion, 1 large Red Bell Pepper, 1 large avocado, 1 large mango
Serve immediately.
Notes
The chicken and the honey lime dressing can be made in advance. I don't recommend prepping the salad ingredients early. It's best if cut and prepared just before serving.
