Baked Greens and Feta Balls

I put this under swiss chard, but you can use any kind of greens you want in it.  When we made it last we used it as a "clean out the fridge" recipe adding chopped radish greens, kale, spinach and chard.  Really good as an appetizer or interesting veggie side!

10 cups loosely packed, finely sliced greens
3-4 tablespoons oil
1 small onion, minced
2-3 garlic scapes, minced
½ cup cilantro (or other fresh herb), chopped
1 tablespoon cumin seeds
1 cup breadcrumbs
1/3 cup feta cheese, crumbled
1-2 eggs

Sauté onion in oil until soft.  Add scapes, cilantro, and cumin for 1 min.  Add greens to wilt.  Remove from heat.  Cool 10 min.  Add rest of ingredients & salt to taste.  Form balls, place on baking sheet, and bake at 375 for 15-20 min.
