Caramelized Onion Cheddar Toast
Soft, browned onions sit under melted cheddar with a little mustard between them and the toast. This is a small meal for a day when you have time to let onions cook slowly. A splash of water loosens the pan as needed. Watch the final broiling closely: the cheese and bread can darken well before you expect them to.

FDA handling and storage conditions
Ingredient substitution
Keep a melting cheddar for the topping. Feta will soften but not create the same melted layer; changing cheese also changes salt, so no exact feta ratio is offered.
