My suggestion is to saute diced mushrooms in your fat of choice (butter or olive oil), and add a sprinkling of salt and a few cracks of pepper. The salt will help the water to escape, which will leave the mushroom a more meaty texture. Saute until the mushrooms look slightly parched, then add a sprinkling of herbs (thyme, oregano) or grated parmesan cheese if you want to be fancy. I've been known to add a splash of balsamic vinegar towards the end of cooking, so it cooks down and glazes the mushrooms, and that takes them to a completely different level. But let's stick with the basic three for now.
Although I'm smitten with mushrooms, I cannot stomach them alone in the absence of other foods. So I try to pair them with something starchy and something strong. Enter: potatoes and herring. We've got a great international deli nearby that sells herring imported from my boyfriend's home country - Belarus. And who can resist fingerling potatoes this time of year? I can't, at least.
As much as I hope this sheds new light on mushrooms, my bigger hope is that you'll enjoy your fall food of choice (apples, squash, parsnips, pumpkin) until you brim with happiness. That's what fall is for - to come back inside from the summer frolics on the beach and restore your energies with nurturing food.
And if you don't cook, reading cookbooks that contain comforting recipes almost does the same trick! Happy fall.
