Season the fish with salt and pepper on both sides. It’s your base layer of confidence.
Heat olive oil in a skillet over medium heat. Add the fish and cook 2–3 minutes per side, until just opaque. Remove and set aside.
In the same pan, add garlic and sauté for about 30 seconds until fragrant. Don’t burn it—garlic is a diva, not a coal mine.
Add cherry tomatoes and olives. Cook 2–3 minutes, until tomatoes start to soften.
Pour in white wine or broth, scrape up any tasty browned bits, and simmer for 2 minutes.
Return fish to the pan. Add lemon juice and zest, sprinkle capers if using, and cook 1–2 minutes more to meld flavors.
Finish with chopped parsley or basil. Adjust seasoning with salt and pepper. Serve hot.
