In the meantime, add avocado, lemon or lime juice, salt, pepper, garlic powder, cheese, chili powder (and the optional liquid smoke, salsa, sour cream, tequila, onion, and olives if using) to a food processor.
Blend until smooth.
Adjust seasonings to taste. You may need a few tablespoons water to get it to blend smoothly.
Stir sauce into hot pasta; mix until cheese melts and everything is warmed through.
