Ancho Chile-Beef Fajitas with Mango
Ground ancho chiles add subtle, earthy heat. If you prefer more spice, substitute chipotle chile powder. To prepare a guacamole side dish, combine 3/4 cup chopped avocado, 1 tablespoon finely chopped red onion, 2 teaspoons chopped fresh cilantro, 1 1/2 teaspoons fresh lemon juice, 1/4 teaspoon salt, and 1/8 teaspoon ground red pepper, mashing to desired consistency. Serve immediately with baked tortilla chips.
