Step 1: Cook the Chicken: Drizzle olive oil in a skillet over medium heat. Season chicken breasts with chili powder, cumin, garlic powder, salt, and pepper. Cook for about 7-8 minutes per side, or until fully cooked and internal temperature reaches 165F (74C). Let the chicken cool slightly, then shred or dice into bite-sized pieces.
Step 2: Prepare the Vegetables: In a large bowl, combine the corn kernels, diced red bell pepper, finely chopped red onion, rinsed black beans, and chopped cilantro. Ensure the vegetables are evenly distributed for a balanced salad.
Step 3: Make the Dressing: In a small bowl, whisk together the mayonnaise, lime juice, and minced jalapeo (if using). Adjust the lime juice and jalapeo to suit the desired level of tanginess and heat.
Step 4: Combine Ingredients: Add the shredded or diced chicken and diced avocado to the bowl with the vegetables. Pour the dressing over the mixture. Gently toss everything together until all ingredients are well coated. Be careful not to mash the avocado too much.
Step 5: Serve: Serve immediately or chill for later. Serve the salad over lettuce leaves for a lighter meal, or with tortilla chips for a heartier appetizer. It can also be used as a filling for tacos or tostadas.
Optional Tips: For a smokier flavor, grill the chicken instead of pan-frying it. To reduce the fat content, substitute Greek yogurt for half of the mayonnaise. If you don't have fresh cilantro, dried cilantro can be used, but the flavor will be less vibrant. Adding a can of diced tomatoes (drained) can enhance the freshness and juiciness of the salad.
