Stand-up taco shells are one of those things that I wished somebody would invent when I was a kid. I stock up when these are on sale. These are awesome and brilliant, just as tacos are awesome and brilliant. When you balance the stand-up taco shell on its bottom, you are maximizing the potential of your taco. It allows you to lay a perfect bed of lettuce, with the succulent and perfectly-seasoned beef, dripping its cumin'd juices into the bed of lettuce below, with a dusting of your favorite finely hand-grated cheese, and a number cherry tomatoes decorating the top - a literal cherry on top of delicious tacoy goodness smothered with hot sauce and sour cream.
