Make the balsamic reduction by heating the olive oil (for the reduction) in a small pot or pan. Add the balsamic vinegar and honey, and simmer until it thickens and reduces, about 5 minutes. Reserve. This step can be done well in advance (hours or a day or two; store at room temp or refrigerated) and the reduction reheated before serving.
2 tbsp olive oil, ½ cup balsamic vinegar, 1 tbsp honey
Heat a non-stick fry pan to medium-high heat. Add 1 tbsp extra virgin olive oil. Add the red bell pepper, red onion, and zucchini to the pan, toss to coat, and sprinkle with salt and pepper. Cook for about 10 minutes or until the veggies are fork tender and browned on the edges. Remove to a plate, cover with foil to keep warm.
1 red bell pepper, 1 red onion, 1 zucchini, 1/4 tsp salt, 1/8 tsp pepper, 2 tbsp olive oil
Add the remainder of olive oil to the pan. With a sharp knife, score the skin of each filet twice. If you are using fish that has no skin such as tilapia or cod, you do not need to score the fish. Salt and pepper the fish fillets on both sides.
4 cod
Lay the fish skin-side down in the hot pan (if there is skin on the fish). The fish may curl; you can give it a little “press down” with a spatula for a minute. Cook for 2-3 minutes, flip and cook the other side for 2-3 minutes.
Divide the vegetables between the plates and lay the fish on top of the vegetables. Drizzle the fish, and around the fish, with the balsamic reduction.
Sprinkle parsley on top.
1 handful parsley
