1 unbaked pie shell
2 medium onions
3 tender chayote or zucchini
2 tbsp. butter
1/2 lb. grated mild cheese (such as Jack cheese)
2 eggs
salt and pepper, to taste

Preheat oven to 350°F.

Chop onions and chayote. Cook in the butter until partly cooked. Add the cheese, salt, and pepper; mix well. Pour the mixture into the unbaked pie shell. Beat the two eggs until fluffy and pour over the chayote mixture.

Bake at 350°F. until eggs are done inside and browned. Cut into wedges and serve warm.

Variation: The chayote can also be made into an omelet by using the above ingredients without the pie shell.
