Chorizo/Beef Picadillo (Chorizo/Beef Filling)

Use as a filling for tacos and flour tortillas.

2 1/2 tablespoons olive oil
2/3 cup green chiles, minced
2/3 cup onions, minced
2/3 cup potatoes, minced
3 cloves garlic, minced
Heaping 1/4 teaspoon salt
Heaping 1/2 teaspoon ground cumin
1/2 teaspoon Mexican oregano
8 ounces chorizo
1 1/4 pounds very lean ground beef

Heat olive oil in a skillet over moderate heat and add green chiles, onions, potatoes and garlic. Saut? the vegetables until they are well browned, adjusting the heat as necessary, about 8 to 10 minutes, stirring often. You may have to add a little more olive oil to keep the vegetables from sticking.

Add tomatoes and continue cooking for 3 minutes, stirring often. Add salt, cumin and oregano and cook for 1 minute. Add chorizo, breaking it up and stirring it into the vegetables. When the chorizo has browned and released most of its fat, add the ground beef, breaking it up and mixing it with the other ingredients. When the ground beef has browned, cover the skillet, turn the heat to very low, and simmer, stirring occasionally, for 10 minutes.

Makes about 4 cups.
