This is one of our old favorites, perfect for when you don't want to cave in to crappy take-out, but just don't have the time or patience to spend more than a couple minutes cooking. It's so simple, it feels silly to write a recipe. So, I won't - I will just tell you what to do. Get a couple of salmon fillets and season them liberally with Cajun seasoning (we like Tony Chachere's the best).
Dice up a tomato, an avocado, a serrano chili (or whatever kind of hot pepper you like), and a little red onion. Combine in a bowl, season lightly with kosher salt and freshly ground black pepper, and squeeze in the juice of one lime. Mix thoroughly. I like to do this immediately upon getting home, then I cover with plastic wrap and let all the ingredients get acquainted in the fridge until dinnertime.
Heat a drizzle of olive oil in a non-stick skillet and cook your salmon, flaking it apart with the spatula as it cooks. This will take like 5 minutes, start to finish. Once it's just cooked through, transfer to a serving dish. In the microwave, warm up some tortillas of your choice (I like La Tortillas) wrapped in a kitchen towel for 30 seconds. Flap out a nice little tortilla on your plate, top with steaming salmon, and adorn lovingly with tomato-avocado salsa.
Serves as many as you like, just scale up. Takes minutes.
