Bring a small pot of water to a boil and add the frozen peas. Cook for 1–2 minutes until just tender, then drain and rinse under cold water to stop the cooking process.
In a large mixing bowl, combine the chopped broccoli, cooled peas, shredded lettuce, diced green pepper, bacon, cashews, and cubed cheddar.
In a small bowl, whisk together the mayonnaise, minced garlic, and dried basil until smooth and creamy.
Pour the dressing over the salad and toss gently until everything is evenly coated.
Chill for at least 30 minutes before serving to allow the flavors to blend.
Serve cold as a refreshing side dish or light lunch.
