Sarah Carey, editor of Everyday Food, says, "Add a teaspoon of sugar to the filling if you like a hint of sweetness (I do about half the time). Making your own shells is easy, but you could also buy them."
Sarah says, "My aunt Colleen made these tacos all the time when I was little, so I call them 1970s tacos (though they're actually pretty classic). The secret is in the filling: Using a few bold flavors and zesty spices is just as easy as tossing in some store-bought seasoning packet, and way more delicious! Now I make them for my kids on special occasions -- like Monday-night dinner."
