Peel the yucca and cut into 1-inch cubes. Place in a large pot of salted water and bring to a boil. Simmer and cook until tender, about 15 minutes. Drain and allow to cool.
Set a large skillet or saute pan over medium-high heat. Add the oil and fry the yucca until crispy, 10 to 12 minutes. Transfer to a paper towel-lined plate to drain and season with salt. Add the peppers, garlic and onions to the pan and saute until well caramelized, 7 to 8 minutes. Season with salt and pepper. Fold the corn, peas and crispy fried yucca back into the pan and heat through. Season with salt, pepper and paprika. Toss to combine everything and serve hot.
