Pan-Seared Grouper with Tomato-Olive Relish

This weeknight-friendly dinner pairs meaty, flaky grouper with a vibrant Mediterranean relish of juicy tomatoes, briny olives, capers, and lemon. Searing the fish in just a touch of olive oil gives it a golden crust while keeping the dish light, and the relish delivers huge flavor without any cream or heavy sauce — just fresh vegetables, acid, and good olive oil doing the work. Each portion is built around a generous fillet of fish for a satisfying dose of lean protein, while the relish adds volume, fiber, and brightness without excess carbs or fat. It comes together in under 30 minutes with one pan and a cutting board, making it an easy, nourishing option for a low-key keto dinner that still feels special. Portions are kept moderate and the plate is light enough to sit easily, even on a smaller appetite.
