There's something very exciting about fajitas, and it's due to more than just that sizzling hot skillet that comes out from the restaurant kitchen. When that unmistakable aroma first hits your nose, you know you're about to embark on an adventure. And a spicy one, too, that will include notes of chili powder, garlic and onion, cumin, and maybe even a pinch of cayenne. This slow cooker version is no different, except that instead of inhaling those intoxicating smells for just a few minutes, you'll be surrounded by them for hours.
But while the aromas may be complex, the recipe is very simple. You mix a quick seasoning blend and then layer traditional onions and peppers into your slow cooker, with flank steak thrown on top. The splash of water is simply to keep the onions and peppers from drying out, but when the seasoning mixes with it, you'll get quite a nice braise.
