“I couldn’t believe how delicious this was, especially for being low in fat.I am now thinking of substituting portabella mushrooms for other recipes since it fills you up, gives a delicious flavor, yet is healthy.Very easy to make too.”
“Great idea for Portobellos, I had never oven roasted them before. I used dry oregano, and added the cayenne for a little kick.”
“These were absolutely delicious!I had the six inch tortillas and wanted to make 4 tortillas. I did not have enough portobella mushrooms, so I filled in with a small can of mushrooms.I drained them and baked them along with portobellos for the last 15 minutes.I baked my tortillas whole and sliced them in half to serve.I served them with diced tomatoes and sour cream.They were great!.Thanks Sue L!”
