Qhich fast food restaurant serves healthy food and the lowest cost?

Subway is often considered a fast food restaurant that offers healthier options, allowing customers to customize Sandwiches and salads with plenty of fresh vegetables and lean proteins. Additionally, many Subway locations have value menus that provide affordable meal choices. Another option is Chipotle, which focuses on fresh ingredients and allows for customizable, healthier meals, though it may be slightly pricier than Subway. Ultimately, the healthiest option at the lowest cost would depend on individual menu choices and local pricing.
