Melt a couple of tablespoons of good-for-you butter in a heavy skillet. Slice zucchinis lengthwise. Add to skillet. Season with your favorite spices. I like onion powder, curry, paprika, pepper and sea salt. Flip when they start getting soft or brown a little. Flip over and add seasoning to other side if you'd like. Be careful not to overcook them. They should not turn translucent, just tender enough to eat.
