How to Make It
Preheat oven to 425°F. Combine the garlic and 3 tablespoons of the oil in a small skillet over medium; cook until the garlic is browned, 2 minutes. Add the panko; cook, stirring occasionally, until lightly browned, about 3 minutes. Stir in the parsley.
Season the cod with the salt and place on a parchment-lined rimmed baking sheet. Top with the panko mixture. Bake until the fish flakes easily with a fork, about 12 minutes.
Heat the remaining oil in a large skillet over medium-high. Add the kale; cook, stirring occasionally, until lightly wilted, 2 to 3 minutes. Sprinkle with the lemon juice. Serve the kale with the fish and tomato wedges.
