I know it sounds a little bizarre, but I came across this video ( about 2:07 minutes in) and I decided to try it. Came out pretty good. Figured Id share.
Basically, sauté up mushrooms and onions in a little olive oils
(I think I added some garlic too)
Season with S&P ( I think they put oregano in it).
***Although I didn't, a few splashes of truffle oil would have worked well. My wife hates truffles, so I didnt add it ***
Blend up mushroom and onion mixture to make kind of a paste.
Lay a flour tortilla on parchment lined baking sheet
Spread thin layer of mushroom mixture, top with another tortilla and repeat.
I did 4 tortillas ( 3 layers oof mushrooms).
On the top of the last tortilla, add a thin layer of sour cream and sprinkle on shredded cheddar.
Bake at about 350F for 15 - 20 minutes.
You'll see, in my pic below, that my cheese doesnt appear melted. Thats because I had to use vegan cheese , which either doesnt melt ( like this one) or melts to a snotty consistency ( which is why I dont use that version).
Specific ingredients and amounts in the video.
