Heat a large non-stick skillet over medium-high heat.
Line the skillet with parchment paper or use a light coating of cooking oil to prevent sticking.
Season the cod filets with sea salt, lemon pepper, and oregano to your taste.
Place the seasoned cod filets in the skillet and cook for about 4-5 minutes on each side, or until the fish is cooked through and flakes easily with a fork.
While the cod is cooking, prepare the vegetables for the Greek salad by chopping cucumbers, vine-ripened tomatoes, red onion, bell peppers, and feta cheese. Combine them in a large mixing bowl.
Toss the salad ingredients together to mix well.
Once the cod is cooked, remove it from the skillet and serve it with the Greek salad. Squeeze fresh lemon wedges over the cod for added flavor.
