Sprinkle the mackerel with salt (not listed in the ingredients), let sit for 5 minutes, rinse under cold water, then thoroughly blot off excess moisture with a paper towel. Season with salt and pepper, then coat in flour.
Remove the seeds from the red bell pepper, thinly slice lengthwise, then microwave (800 W) for 1 minute. Thinly slice the onion and julienne the carrot.
In a bowl, combine the ★ ingredients and add the vegetables from Step 2.
In a frying pan, heat the olive oil over medium heat. Arrange the mackerel in the pan, cover with a lid, then fry both sides until golden brown.
Transfer the fish to a serving dish, pour the sauce over it, then serve.
