Bring a pot of salted water to a boil. Cook the pasta in the boiling water until al dente according to the package instructions. Drain and transfer to a large bowl.
Toss the pasta with the Honey-Chipotle Vinaigrette. Season with salt and pepper. Next, add the chicken, cherry tomatoes and banana peppers. Toss it all and transfer to a pasta bowl for serving. Top with fanned-out avocado slices and garnish with the chives.
Put the vinegar, mayo, honey, chipotle, mustard, Italian seasoning, garlic and some salt and pepper in a blender or food processor. While the machine is running, slowly drizzle in the olive oil until the dressing is combined and emulsified. Adjust the seasoning if necessary, or add more chipotle if you want it more spicy.
