6 cups chopped beet greens (or whatever greens you have - I used spinach and swiss chard and beet greens)
3 large eggs
1/2 cup whole wheat flour
1/2 cup milk
1/2 cup grated cheese
salt (to taste)
Preheat oven to 350. Grease the bottom and sides of an 8 x 8 baking dish with about 1 tbsp of the butter. Heat a large skillet and begin to saute the onion in 1 tbsp of olive oil. Cook until onion begins to brown and soften. Make sure your beet greens are well cleaned and very dry. Add beet greens and a sprinkle of salt. Cook until beet greens are just tender. Drain off excess liquid given off while cooking.
While the onion and beet greens cook whisk the eggs, milk and flour into a smooth batter. Stir in the cheese. Put 1 tbsp of butter in the baking dish and place in the warm ofen until the butter melts. The swirl it around the bottom of the dish. Put the onion and beet green mixture in the baking dish. Pour the batter evenly on top.
Cook for about 30 minutes in the center of the oven until puffed and golden. It will deflate a bit while cooling.
