What can I use instead of onion flakes?

Onion flakes, usually sold in the dried herb and spice section of the grocery store, are simply dehydrated, chopped onions. Instead of 1 tablespoon of onion flakes, try 2 to 3 tablespoons of jarred minced onion, 3/4 to 1 teaspoon of onion powder, 3/4 to 1 teaspoon of onion salt (and reduce the amount of any other salt added to the recipe), 1/2 cup chopped fresh or frozen onion, or 2/3 cup of chopped green onions.
