Zucchini Frittata

I've used diced zucchini in my omelettes, but grating it works better. For a particularly rich result, whisk together the eggs, the cream, and the cheese; then work in the zucchini. Pour this mixture over sauteéd onions and cook until firm through and through.

- 4 eggs
- 1 Tbsp half-and-half or cream
- 1/4 cup Parmesan cheese, grated
- zucchini, grated
- onion
- butter
