Gourmet Onion Mushroom Burgers
Dijon mustard originated in Dijon, France, and was originally made from brown or black mustard seeds and verjuice, a juice made from unripe grapes. Dijon mustard has a more pungent flavor than yellow mustard, and shouldn't be substituted.

Onion Storage
Onions should be stored in a cool, dry place with good air flow. They shouldn't be stored in the refrigerator or in plastic bags, but onions can also be frozen. To freeze the onions, chop them and flash freeze on a baking sheet. Transfer to a freezer bag. When a recipe calls for chopped onion, you can measure right from the freezer bag.
