Notes

  • Mushrooms: Cremini or brown mushrooms will bring more savory, mushroom flavor than white mushrooms.
  • The thickness of the bread: Be sure to cut the toast a bit on the thicker side so they don't get soggy from the mushrooms.
  • Liquid in the skillet: Most of the water should cook out of the mushrooms but if you still see liquid, drain it off before you add the remaining ingredients.
If you want others to look at you in awe and sing your praises. Serve these toasts and a few other finger foods on a platter at your next party or get together. People will think you're a master chef and tell others of your greatness!
