Step 1

Cut the steak into bite-size pieces.

Step 2

Heat oil in a large skillet.

Step 3

Add half the onion into the skillet and cook until soft, for 5 minutes.

Step 4

Add the steak and season it with salt and pepper and lime juice.

Step 5

Cook the steak until cooked through.

Step 6

While the steak is cooking, heat half the butter in a second skillet over medium heat. Fry half the mini tortillas for 1 minute. Heat the remaining butter and cook the remaining four tortillas.

Step 7

Allow the tortillas to cool slightly, then stack them in pairs of two so you have four taco shells in total.

Step 8

Divide the meat among the tortillas. Top the meat with reserved onions and chopped cilantro.

Step 9

Serve tacos warm with fresh lime wedges.
