Oregano has a hot, peppery flavor.  Greek oregano is the very best of the oregano plants, with the best taste.  Where you taste oregano the most is pizzas, and spaghetti with tomato sauce, but it also enhances omelets, quiches, stewed beef, pork, poultry, wild game, onions, potatoes, and eggplant.  It can also be used for coughs, headaches, tonics, and used as a stimulant.  An Italian blend of herbs are: oregano, basil, rosemary, majoram and can be used in any tomato dishes, so give it a try.  The Herb Lady

Marjoram has a distinctive savory flavor.  Marjoram is suited for thick stews, vegetable soups, pasta, fish, game, beef, and chicken, but don’t limit using it for just these foods.  When cooked it enhances the flavor of other foods or herbs.  To increase its potency, use generous amounts and include the stems which are more strongly flavored.  I use it in all my pea, bean, and tomatoe dishes.  It is also good in omelets and cheese dishes.  This is one of my most favorite herbs.  The Herb Lady
