Tuna Taco

After that picture of Paris Hilton's big tuna, how about a recipe for a tuna taco?

1 3-ounce ahi tuna steak, cut into 1-inch cubes
1 teaspoon fresh lime juice
1/4 teaspoon cumin
1 corn tortilla, warmed
1 plum tomato, diced
1/2 cup shredded romaine lettuce
1 tablespoon store-bought guacamole

In a small bowl, toss the tuna with the lime juice and cumin.

Heat a nonstick skillet over medium-high heat. Add the tuna and cook, stirring occasionally, to desired doneness, about 4 minutes for medium rare. Transfer to the tortilla. Top the tuna with the tomato, lettuce, and guacamole. Fold into a taco.

Yield: Makes 1 serving
