• Step 1: Preheat your oven to 400°F (200°C). Season the chicken breasts with salt and pepper, then place them on a baking sheet. Bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C). Allow the chicken to cool, then shred or dice it into bite-sized pieces.
• Step 2: In a large bowl, combine the shredded or diced chicken, chopped basil, chopped romaine lettuce, halved cherry tomatoes, and sliced red onion.
• Step 3: In a small bowl, whisk together the olive oil, lemon juice, Dijon mustard, and minced garlic. Season the dressing with salt and pepper to taste.
• Step 4: Pour the dressing over the salad and toss gently to coat all the ingredients evenly.
