This easy 7-Layer Pasta Salad combines al dente farfalle with fresh broccoli, diced ham, and shredded cheddar, layered with creamy avocado, crisp romaine, and juicy tomatoes. It's bound by a zesty buttermilk-mayonnaise dressing with fresh herbs and lime. Perfect for a quick, vibrant side or light meal, best served after a gentle toss to distribute flavors.
To ensure perfectly cooked pasta, boil until al dente and immediately rinse with cold water to halt the cooking process and prevent stickiness; this also helps cool it down for the salad. For the broccoli, aim for tender-crispness, not mushy. The key to the dressing is balancing the tangy buttermilk with the fresh herbs and lime juice; adjust seasoning to taste. When dicing avocados, toss them immediately with lime juice to prevent oxidation and browning, maintaining their vibrant green color. While the layered presentation is visually appealing, gently toss the salad just before serving to ensure every bite is coated with the delicious dressing and a mix of all ingredients. If preparing ahead, store the dressing and layered salad separately, combining and tossing right before serving for optimal texture and freshness.
