Whisk together the ½ cup olive oil, 3 tablespoons apple cider vinegar, 2 tablespoons chopped cilantro, 1 tablespoon honey, 3 minced garlic cloves, 1 tablespoon lime juice, 1 teaspoon ground cumin, 1 teaspoon paprika, 1 teaspoon salt, and ½ teaspoon lime zest.
Marinate the 1 pound boneless skinless chicken breasts in HALF of the dressing for 10 minutes, reserving the rest for the salad.
Heat a grill pan and place the chicken breasts on it. Cook the chicken on each side for 4-5 minutes. Let the chicken rest for 10 minutes and then slice.
In the same grill pan, add the 1 cubed red bell pepper and 1 sliced red onion along with a tablespoon of the dressing, and grill on high heat to lightly char. Remove and set aside.
To assemble the salad, place 2 heads chopped Romaine Lettuce at the bottom of the bowl. Place red bell peppers, onions, chicken, and 1 cup mango salsa on top. Drizzle with the remaining dressing. Toss and enjoy!
