Preparing for a party? Stuff, cover and refrigerate the mushrooms up to 24 hours ahead. Then when you're ready for hot appetizers, simply start with step 4.
If you use Italian-seasoned bread crumbs, you can decrease the Italian seasoning to about 1 teaspoon.
Italian seasoning is a premade seasoning blend that usually includes: basil, marjoram, oregano, rosemary, sage, savory and thyme.
When using dried spices and seasoning blends, store in airtight container away from heat, light and moisture. For best flavor, keep whole spices and herb leaves up to 1 year and ground spices and herbs up to 6 months. Older spices and herbs can be used, but the flavors will weaken with age.
Use a small ice-cream scoop or the large end of a melon ball cutter to scoop the vegetable mixture evenly into the mushroom caps.
