Havana Omelet

Put two tablespoonfuls of butter and two chopped onions over hot water until the onion is soft and thoroughly cooked. Peel four tomatoes, cut them into halves and press out the seeds. Then cut each half into quarters, add four Spanish peppers cut in strips, a level teaspoonful of salt and a dash of red pepper. Cook until the tomato is soft. Make a six-egg omelet. Turn it onto a heated platter, put the tomato mixture at the ends, and send at once to the table.
