Wash the pepper, cut off the top, remove the seeds and partitions. If you like the pepper to be soft after cooking, you can lower the peppers into boiling water for 2-3 minutes. I didn't do it, I like it when vegetables are cooked al dente. The inner walls of the peppers can be lightly salted, if you like salty dishes, I do not salt. Chop the mushrooms and herbs, grate the cheese on a medium grater.
