Bring a large pot of water to a boil and cook the pasta according to package directions. Drain and rinse with cold water, then set aside.
Heat avocado oil in a skillet over medium heat. Add chickpeas and dry seasonings (garlic powder, smoked paprika, pepper) and cook for about 3 minutes until chickpeas become crispy.
Add buffalo sauce to the skillet with chickpeas and cook for another 2 minutes, stirring frequently. Remove from heat and let cool.
Combine vegan mayo, green chiles, garlic cloves, onion powder, dried parsley, dried chives, dried dill, pepper, and apple cider vinegar in a food processor or blender. Blend until smooth and adjust seasonings to taste.
In a large bowl, combine the cooked pasta, diced bell pepper, halved tomatoes, chopped cilantro, diced red onion, chopped avocado, cooked buffalo chickpeas, and green chile ranch dressing. Toss gently to combine.
Top the salad with diced green onions and serve immediately or chilled.
