How to Make It
Light a grill. Heat the peanut oil in a large skillet over high heat to 375°. Fry the plantain slices in batches until crisp. Drain on paper towels and reserve.
Brush the squid with 2 tablespoons of the olive oil, season with salt and pepper and grill for 3 minutes on each side. Alternatively, heat the remaining 2 tablespoons of olive oil in a large skillet over moderately-high heat until smoking, then sauté the squid until golden on all sides. Remove from pan and cut in half or into 2 inch pieces.
In a large bowl, toss the squid with the mangoes, arugula and the vinaigrette. Season with salt and pepper. Heap the salad onto a large platter and garnish with the fried plantains, diced bell pepper and mint leaves.
