Char the corn on the cob (if you are using frozen corn kernels just skip this step) Shuck the corn if needed, add it to an open flame on your stovetop and turn often until charred lightly OR grill it for just a few minutes on medium heat on the grill, turning often. Start the pasta, this take about 20 minutes, cook according to the package. Next, Prepare the ingredients, use a sharp knife to slice and dice everything into bite sized pieces and cut the corn off the cob once it's cooled.
Add all the dressing ingredients to a food processor and blitz. Add more water if needed to thin the sauce. (limes, mayo, sour cream, sriracha, fresh cilantro, seasonings, water)
Add everything to a large bowl (pasta, veggies, chicken, cheese, avocado, dressing). Pour 3/4ths of the dressing on top and mix well until everything is evenly dressed. The rest is used for garnish.
Add extra garnishes (lime wedges, more cilantro, tajin etc), extra dressing drizzle and a few lime wedges and serve room temperature or chilled
