Tacos are a terrific midweek meal because they cook up fast and don’t require a lot of preparation, other than some chopping and dicing of ingredients. This super-easy steak taco recipe hits all the right notes with its flavorful chili-lime marinade and array of colorful toppings, many of them in bountiful supply at local farmers markets and roadside farm stands.
