In a medium saucepan, prepare the rice according to package instructions. Once cooked, set aside and keep warm.
While the rice is cooking, season the chicken breasts with smoked paprika, chili powder, salt, and pepper.
Heat olive oil in a large skillet over medium heat.
Add the seasoned chicken to the skillet and cook for approximately 6-7 minutes on each side, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C). Remove from heat and let it rest for a few minutes before slicing into strips.
In a mixing bowl, combine the drained corn, mayonnaise, crumbled feta, chopped cilantro, and lime juice. Mix until well combined.
In each bowl, start with a base of cooked rice, then add a portion of the sliced chicken on top. Generously spoon the street corn mix over the chicken.
If desired, top with sliced jalapeños and serve with extra lime wedges on the side.
