Preheat your oven to 400°F. Slice the bell peppers into thin strips and place them on a baking sheet.
Drizzle the peppers with a small amount of olive oil and a pinch of salt, then roast for 15 minutes until tender and slightly charred.
Season the chicken breast evenly with garlic powder, dried oregano, sea salt, and black pepper.
Heat a non-stick skillet over medium-high heat. Cook the chicken for 6 to 7 minutes per side until the internal temperature reaches 165°F and the exterior is golden brown.
Bring a small pot of water to a boil and cook the shelled edamame for 4 to 5 minutes until tender, then drain and set aside.
Roughly chop the romaine lettuce, baby spinach, and tomato into bite-sized pieces.
Once the chicken has rested for 5 minutes, slice it into thin strips.
In a small bowl, whisk together the remaining extra virgin olive oil and balsamic vinegar to create the dressing.
In a large salad bowl, combine the lettuce, spinach, tomato, roasted peppers, edamame, and chicken.
Pour the dressing over the salad, toss thoroughly to coat, and top with fresh avocado slices before serving.
