tablespoon olive oil
4 cloves garlic, chopped
1 can (28 ounces) whole peeled tomatoes in puree
2 canned chipotle chilies in adobo, finely chopped (about 1 heaping tablespoon), plus 1 tablespoon adobo sauce (from same can)
1 small cooked rotisserie chicken (about 1 3/4 pounds), skinned and shredded (about 4 cups), carcass discarded
1/2 cup lightly packed cilantro leaves, chopped, plus 4 sprigs for garnish
4 cups (about 3 ounces) tortilla chips
1/4 cup reduced-fat sour cream
1.75 ounces feta cheese, crumbled (about 1/4 cup)
Combine oil and garlic in a large (3-to-4-quart) saucepan. Cook over medium heat, stirring occasionally, until fragrant and sizzling, 1 to 2 minutes.
Add tomatoes with their puree (breaking tomatoes up), chipotles and adobo, and 1 cup water. Bring to a boil; season with salt.
Reduce heat and simmer rapidly until lightly thickened, 6 to 8 minutes.
Add chicken and cook, stirring, until hot, about 1 minute. Remove from heat; stir in chopped cilantro.
Divide chips among four shallow bowls; top with chicken mixture and sauce. Garnish with cilantro sprigs, sour cream, and feta. Serve
