Carnitas Sandwiches with Avocado Salsa

4 pounds boned pork shoulder, cut into large cubes
    (remove as much fat as possible)
1 quart (4 cups) beef broth
1 (16 ounce) jar chunky tomato salsa
Water
3 ripe Hass avocados, seeded, peeled, diced
2 cups fresh pico de gallo salsa (recipe follows)
8 sandwich rolls or buns, split lengthwise (see note)
Sour cream, for garnish

In large heavy saucepan over medium-high heat, combine pork chunks, broth and salsa. Add enough water to completely cover meat. Cover and bring to a boil. Reduce heat to low and simmer (covered) for 3 to 4 hours or until meat pulls apart easily.

Heat oven to 400 degrees F.

Remove meat from liquid in pot (discard liquid) and place in a roasting pan. Break meat into small chunks. Roast meat for 15 to 20 minutes until brown and crispy (carnitas).

While meat is roasting, combine avocado dice with prepared pico de gallo salsa.

To serve, spoon carnitas into sandwich rolls and top with avocado salsa and sour cream. (Meat can be prepared in advance and transported to a picnic or party.)

Makes 8 servings.
