A Boulder, Colorado, company is recalling more than 15,000 pounds of frozen chicken and steak fajita products.  Phil's Fresh Foods, Inc., says the products have been misbranded -- the chicken fajita packages may contain steak and the steak fajita packages may contain chicken.  The USDA's Food Safety and Inspection Service says the products come in 7-ounce cartons and are labled "EVOL. BURRITOS FIRE GRILLED CHICKEN FAJITA" or "EVOL. BURRITOS FIRE GRILLED STEAK FAJITA."  For identification purposes, the USDA says the products bear the establishment number "EST.21015" or "P-21015" inside the USDA mark of inspection on the package and the identifying lot number "03311" on the inner plastic packaging.  The fajitas were manufactured on February 2nd and 3rd of this year and were distributed to retail establishments nationwide.
