Start by seasoning the chicken fillets with salt, black pepper, smoked paprika, and garlic powder. I like to rub the spices in well so every bite is flavorful. Set them aside while you prep the other ingredients.
Heat olive oil in your skillet over medium-high heat. Add diced chorizo and cook for about 3 minutes until it crisps. Stir in the corn and half the minced garlic, cooking until golden brown. Finish with oregano, a pinch of salt, and pepper, then remove from the skillet but keep the flavorful oil.
Melt butter in the same skillet, then add the chicken fillets. Cook for about 5 minutes per side until golden brown and fully cooked. I like covering the skillet briefly to ensure even cooking. Remove the chicken and place it on a plate, covering with foil to rest.
In the same skillet, sauté the chopped onion and remaining garlic over low heat for 1–2 minutes. Deglaze the pan with white wine, scraping up the browned bits. Simmer for 2 minutes, then add milk and cream cheese, stirring until smooth and creamy.
Return the chicken to the skillet, pouring any juices back in. Let everything cook together for about 5 minutes until the chicken is heated through and coated in the creamy sauce. Top with the crisped corn, chorizo, red pepper flakes, and chopped chives before serving.
