Slice the beef across the grain into 1/4-inch slices. Combine in a mixing bowl with the oil, salt and pepper. Toss well to coat. Heat the grill or heat a dry cast iron skillet until smoking. Sear the meat until light pink in the center, about 30 seconds per side. Transfer to a cutting board. Cut into 1/2-inch wide strips and reserve in a bowl with the juices. For carne asada tacos, toast 24 small Corn Tortillas and keep warm. For each taco, stack two tortillas and layer with carne asada strips. Top with a tablespoon of Pureed Tomato Salsa Cruda. Garnish with shredded white cabbage, scallions, thinly sliced radishes and avocado slices.
Pureed Tomato Salsa Cruda:
Combine all of the ingredients in a blender and puree until smooth.
