When I was a kid I hated all the traditional food that kids hate - spinach, brussel sprouts, green beans - but I loved beet greens. I still do. Here's one of my favorite ways of preparing them
1 large or 2 small bunches of beet greens
2 TB butter
1 tsp Dijon mustard
1/2 to 1 tsp prepared horseradish
salt, pepper
Wash greens well and steam until almost done. The time required wll depend on the greens; young fresh ones take only a few minutes. Drain and chop coarsely. Melt the butter in a saute pan and add the greens, mustard, and horseradish. Mix well, cover, and cook slowly for a few minutes. Add S&P to taste and serve.
