From 'Vegetarian' by Linda Fraser with only a few small changes. Baby spinach or Swiss chard can be used instead of beet greens. Reminder: beet greens and Swiss chard require a little longer cooking time than baby spinach. For a less aggressive garlic presence, use mildly-flavored garlic whistles/scapes. Final comment: I thought the recipe was lacking something to take the dish to the next level. What pairs well with beets/beet greens? Ah, allspice!
