Prepare the Chicken:
Cook the chicken breasts by grilling or pan-searing them in a skillet over medium heat for about 6–7 minutes per side, or until fully cooked. Let the chicken rest for a few minutes before slicing it into strips.
Prepare the Bacon:
While the chicken cooks, crisp up the bacon in a skillet over medium heat for about 4–5 minutes per side. Once cooked, crumble the bacon into small pieces.
Assemble the Salad:
In a large bowl, add the mixed greens, avocado, hard-boiled eggs, bacon, blue cheese, tomatoes, cucumber, and red onion.
Make the Dressing:
In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, salt, and pepper until smooth and emulsified.
Toss the Salad:
Drizzle the dressing over the salad ingredients and toss gently to combine, ensuring everything is evenly coated.
Add the Chicken:
Top the salad with the sliced chicken, either tossing it into the salad or arranging it on top as a garnish.
