In a small bowl, season chicken cutlets with fajita seasoning and 1 tablespoon olive oil.
Place in the fridge to marinate while preparing the street corn.
In a mixing bowl, combine corn, cotija cheese, chili powder, mayonnaise, lime juice, salt, and cilantro. Stir until well mixed.
Heat a skillet over medium-high heat with the remaining olive oil.
Cook chicken 4–5 minutes per side, or until fully cooked through.
Remove from the skillet and slice into strips or dice into cubes.
To assemble, divide rice between two bowls. Top with chicken and corn mixture.
Garnish with red onion, crumbled cotija cheese, and chopped cilantro.
Serve immediately and enjoy!
