Preheat the oven to 400°F.
Mix the breadcrumbs, lime zest, chili powder, cumin, salt and pepper in the plastic bag and toss to combine.
Add the chicken to the bag, a couple pieces at a time. Seal the bag and give it a good shimmy-shake to coat the chicken.
Place the coated chicken on a baking sheet and repeat with remaining chicken until all the pieces are coated. Bake for 40-45 minutes, or until cooked through.
Into a container with a lid, add the lime juice, garlic and EVOO. In a salad bowl, add the tomatoes, red pepper, red onion and romaine, and pour dressing over the salad.
Season with salt and pepper, sprinkle with chopped cilantro and toss to coat. Serve salad alongside the chicken.
