Combine flour, salt, and pepper on a large plate. Dredge fillets in flour mixture, coating both sides.
Heat olive oil, lemon juice, and lime juice in a very large nonstick skillet over medium-high heat. Cook fillets 2 to 3 minutes on each side or until done. (If liquid reduces too much, add about 1/4 cup water.) Serve immediately.
Wine pairing: A Fumé Blanc, Sauvignon Blanc, or crisp Chardonnay will complement any citrus-seafood dishes (perhaps served with a tossed green salad and crusty French bread) for a light, refreshing supper.
