This is a recipe that I improvised earlier this summer, riffing off a Joy of Cooking recipe. Ooh, it was good.
Wash and pat dry two salmon fillets, and place into a glass baking dish. Generously drizzle with olive oil, season with plenty of salt and fresh cracked black pepper, and five cloves of crushed garlic. Rub this mixture into the salmon and allow it to marinate for a few minutes. Drizzle with a bit of soy sauce and some seasoned rice vinegar. Dump on half a pint of cherry tomatoes, one very thinly sliced onion, and a generous handful of cilantro leaves, coarsely chopped. Drizzle more olive oil on top. Spread the vegetables & herbs around in the pan to mix with oil and spread evenly in the baking dish. Broil about 8 inches from the flame until onions are carmelized and fish is done, about 10-15 minutes.
