Food Delivery/Cantina in Miami

Any recommendations for a Food Delivery or a Cantina in Miami-Dade area to replace home cooked meals for an elderly parent? I don't cook and going out for food and ordering in has become expensive and time consuming. I'm also not home regularly and just want to have an answer to "what's for lunch/dinner ?" when it comes to catering to my elderly mother who used to cook Cuban food on a regular basis.
