Cook pasta and blanch broccoli: Bring a large pot of salted water to a boil. Cook 12 ounces farfalle (bowtie) pasta according to package directions until al dente. In the last 10 minutes of cooking, add 4 cups broccoli florets, chopped small to the pot to blanch.
Cool down: Drain the pasta and broccoli together, then rinse immediately under cold water until fully cooled. Drain well and set aside.
Make the jar: In a small bowl, shake up plain Greek yogurt, good quality mayonnaise, lemon, juiced, dijon mustard, honey, salt, black pepper, and garlic powder until smooth.
In a large bowl, combine the cooled pasta and broccoli with chickpeas, red onion, finely diced, and sharp cheddar. Pour the dressing over and toss to coat evenly.
Add dill and chill: Fold in fresh dill. Chill at least 60 minutes before serving for best flavor.
