They go by several other names too (Miniature Watermelons, Mouse Melon), but I never had them until last week in Georgia. They cut them in half and put them in salads at our inn along with the cherry tomatoes, etc. Crunchy, refreshing little cucumber-like things about an inch long. Grow prolifically on vines. Be the first in your neighborhood. I ordered some seeds right away.
Another good thing they grew in their gardens was a tangy peppery green which is new to me, Curly Mustard, or Mustard Mizuna. Use it when the leaves are young.
And lots of Mache, of course. Down there, you must do many sequential plantings of greens, but in summer they must be shaded.
