In a pan over low heat, sauté the garlic in the olive oil until soft, about 8 minutes. Remove the garlic bits from the pan and set aside in a small dish, then increase the heat under the pan to medium.
Season the tilapia on both sides with salt and pepper. Sauté the fish in the garlic oil, about 3-4 minutes on each side. Serve with a spritz of fresh lemon juice, chives, and a spoonful of the sautéed garlic on top.
