Heat olive oil in a skillet over medium-high heat. Add diced chicken and season with Cajun seasoning, paprika, garlic powder, onion powder, chili powder, salt, and pepper. Sear for 6–7 minutes until golden. Add butter, garlic, lemon juice, Dijon mustard, and parsley; toss until coated.
In a separate skillet, melt butter. Add corn, garlic powder, paprika, salt, and pepper. Cook until lightly charred, then mix in cheeses until creamy.
Warm tortillas, layer chicken and cheesy corn, then add rice, beans, or sour cream if desired. Roll tightly.
Lightly butter a skillet and crisp burritos 1–2 minutes per side until golden.
Slice, garnish with cilantro, and enjoy warm.
