Preheat a skillet over medium-high heat with 2 tbsp EVOO and the butter. Add the onions, jalapenos, bell peppers, garlic, corn, salt and pepper. Cook for 4-5 minutes or until the onions are tender. Sprinkle with flour, and continue to cook for 1 minute. Whisk in the chicken stock and milk. Bring the corn up to a simmer and then lower the heat to medium-low and add in cornstarch; cook until thick and creamy, about 5 minutes. Finish the corn with parsley and cilantro.
