Spray a baking sheet with a cooking oil spray. Preheat the oven to 400 degrees.
In a small food processor, combine sour cream, lime zest, lime juice, cilantro, and salt. Pulse until smooth. Set aside.
In a medium bowl, combine chicken, beans, corn, and BBQ sauce. Mix until evenly coated.
Lay tortillas out on a clean work surface, and then divide the chicken mixture evenly in the center of each tortilla. Roll them up, and then place them on the prepared baking sheet.
Spray the top of each rolled taquito with cooking oil spray, and sprinkle with kosher salt.
Place the baking sheet into the preheated oven for 7-10 minutes, or until the edges are crisp and golden brown.
Remove the baking sheet from the oven, and sprinkle the cheese and red onions over the taquitos. Return them to the oven for an additional 3-5 minutes, or until the cheese is melted and bubbly.
Remove the taquitos from the oven, drizzle with cilantro lime cream, and top with fresh cilantro and lime wedges. Serve immediately.
