In a bowl, add mango, jalapeno, cilantro, red pepper and red onion. Mix together. Set aside.
In a large heavy saucepan, add the oil and heat to 365 degrees F. Carefully place plantains into pan. Fry until golden brown, about 3 to 4 minutes. With a slotted spoon, remove plantains, season with salt, and let cool. When ready to serve, add mango salsa to "plantain chip".
