Step 1

In a large skillet, cook bacon over medium heat until crisp, stirring occasionally. Remove with a slotted spoon; drain on paper towels.

Step 2

Sprinkle fillets with salt and pepper. Add fillets to bacon drippings; cook over medium-high heat until fish just begins to flake easily with a fork, 4-6 minutes on each side. Remove and keep warm.

Step 3

Add tomatoes to skillet; cook and stir until tomatoes are softened, 2-4 minutes. Stir in vinegar; reduce heat to medium-low. Cook until sauce is thickened, 1-2 minutes longer. Serve cod with tomato mixture and bacon.
