Support short abstract

Is your feature request related to a problem? Please describe.
Make additional information available on the overview page. Examples:

name: "Ciabatta", "abstract:  "Pure sour dough bread"
name: "Tomato Soup",   abstract:  "Original italian style"
name: "Roastbeef",   abstract:  "Cross on the outside, juicy on the inside"

Describe the solution you'd like
CreativeWork items like Recipe support an abstract field. This could be used to add a small amount of information in addition to the recipe's title to add a little more context. The abstract/subtitle/.. could, e.g., be displayed on the recipes overview page with, next to, instead of the creation and modification date (does anyone "use" the dates anyway? 😄). One could also think of showing the info in an overlay on hover (on desktop) and use a different style for mobile devices.

Edit: Just found the disambiguatingDescription property. This might be even better suited.

Start at the recipe overview page and trace how Recipe or CreativeWork data is loaded and rendered. Clarify whether the supported field is abstract or disambiguatingDescription, define its placement alongside or instead of the dates, and verify the result in desktop and mobile browser views.
