  • 1 Red Onion Peeled and sliced thinly.
  • 2 Hass Avocados Peeled and sliced. Can be done when sandwich is being put together.
  • 1 Large Tomato Sliced thinly.

Dairy

  • 4 cups Buttermilk
  • 3 tbsp Butter
  • 8 Slices of your Favorite Cheese

Pantry

  • 9 oz Zatarain's Chicken Fry Mix May substitute for your preferred brand.
  • 1/2 cup Flour

Bread

  • 4 Kaiser Rolls

Oil

Sauce

  • 1/2 cup Ketchup
  • 1/4 cup Mayo
  • 1/4 cup BBQ Sauce
  • 2 tbsp Mustard

Instructions
 

Batter Preparation

  • Place 3 cups Buttermilk in a Bowl and place 1 cup in another. Add Sliced Mushrooms into 3 cup bowl and let it marinade for 30 minutes being sure Mushrooms are covered in Buttermilk. Meanwhile place Onions in the other. Give it a stir a couple of times throughout process.
  • Place 1/2 of Box of Zatarain's Chicken Fry Mix and 1/2 of Flour in a large Ziplock Bag and Shake to incorporate. I start with 1/2 of fry mix as the Buttermilk will cause it to get gummy and will be harder to coat Mushroom and Onions. Can add in more mix & flour as you go along.
    ***I found the Mix to be a little more well seasoned than I like. Adding the additional flour assists with taming down the saltiness of it.

Frying

  • Fill Skillet with enough oil to cover Mushrooms while frying. Heat on medium/high until reaches 350℉ and ready to go.
  • Remove several Mushrooms from Buttermilk being sure to shake off excess and add directly into Flour mixture. Do not overcrowd. Seal and shake to cover Mushrooms thoroughly. Place into hot oil and fry for 5-7 minutes or until crispy and golden brown being sure to flip over midway. Remove and set on paper towel lined plate to absorb excess oil. Continue process until all Mushrooms are fried.
  • Following the same process as Mushrooms. Remove from Buttermilk, add to same Ziplock bag with Flour Mixture and shake to coat. Fry for 2-3 minutes or until golden brown and remove. Place on paper towel lined plate until ready to use.

Meanwhile

  • Spread the Butter on each side of Kaiser Roll. Heat a small skillet on Medium. Lay Kaiser Roll Butter side down and toast the Bread until lightly browned and remove.
  • In a small bowl, add all the ingredients for sauce and stir to incorporate.

Assemble

  • Place a slice of Cheese on bottom of Kaiser Roll while it is hot out of Skillet to help melt the Cheese. Add a generous amount of Fried Mushrooms, another slice of Cheese. Place a few rings of Fried Onions. Drizzle your sauce on top. Top off with sliced Tomato and Avocado and the top portion of your Kaiser Roll. Serve with your favorite sides and ENJOY!!!
