Lake Forest-based Del taco, once known for thick shakes and tasty fries, is mixing things up with the addition of new menu items for the health-conscious consumer. Featuring freshly sliced avocados, its new Fresca bowls are a part of Del Taco’s commitment to provide fresh and quality ingredients at a great price. Del Taco is adding avocado to Fresca bowls based on the success of its “Epic Grilled Chicken Avocado Burrito,” which was released early last year. The new avocado-fresh bowls were released last week, and are priced under $5.00. “Fresh sliced avocados have quickly become a guest favorite,” according to executive vice president, and chief brand officer John Cappasola.
