Season the chicken: Add the cubed chicken to a bowl and toss with avocado oil, salt, pepper, garlic powder, chili powder, paprika, and cumin until evenly coated.
Cook the chicken: Heat a skillet over medium-high heat. Add the chicken and cook, stirring occasionally, until fully cooked and lightly golden on the outside. Remove from heat and set aside.
Make the street corn salsa: In a medium bowl, combine the cooked corn, Greek yogurt, cotija cheese, lime juice and zest, cilantro, avocado, and chili lime seasoning (if using). Stir gently until combined.
Assemble the bowls: Spoon rice into bowls, top with the seasoned chicken, and finish with a generous scoop of the street corn salsa.
Serve: Serve warm with extra lime or cilantro if desired.
