Heat Oil: In a large skillet, heat 4 tablespoons of extra virgin olive oil over medium-high heat.
Cook Aromatics: Add chopped onion, bell pepper, diced tomato, the white parts of green onions, and minced garlic to the skillet. Cook, stirring occasionally, until they start to soften, about 5 minutes.
Add Vegetables and Seasonings: Stir in frozen carrots and peas, sweet kernel corn, salt, ground black pepper, and paprika. Continue to cook and stir until the peas and corn are thoroughly heated, about 5 minutes. Taste and adjust the seasoning as needed.
Cook Tilapia: Add the Tilapia to the skillet and cook it gently for 5 minutes, stirring occasionally.
Add Final Touches: Stir in chopped parsley and the green parts of the green onions. Set the skillet aside to let the filling cool.
