Flowers! Last year we were short on time as well and divided the patches with broad strips of flowers and herbs.. This reduces your full m2, it is a beautiful sight, good for the bees and when they are done: just rip the flowers out and put on your compost heap. (I do have about 40 thyme plants now ..)
We used calendula a lot, Tropaeolum magus: the eatable flower, chrysantium, Tagetes (the big ones), camomile, thyme, salvia, rosemary.
Leafy beets are good as well: strong and need little attention apart from harvesting and eating.
As mentioned before: different kinds of pumpkins and Artichokes: in the evening the flowers will be full with bumble bees, who sleep in the flower! The sight will make you happy.
The experience I have on the plot is like SnooziSusi says: communicate with the board and things are a little more relaxed..
