Grilled Mushroom and Cheese Sandwich Recipe

Have you ever felt that instant and deep connection with something that’s so powerful it sets your life on a new trajectory? I kind of feel like that about this sandwich. It is so hard for me to find something that I like, is easy, is cheap, and is flexible enough to really make it into my fall-back recipes. Those things you can make blind-folded and know that it will taste good. Especially those nights where you can’t even be bothered to call for pizza. Well ladies and gents, I have found my new fall-back. Please let me present the grilled mushroom and cheese sandwich.

Listen to this and see if you can’t find the appeal. You can use any cheese you want, so long as about half of it is “melty”. You can take your pick of mushrooms. And spices. And did I mention this is also a great base recipe to throw in any miscellaneous produce that’s ready to kick it? I’ve thrown in peppers, sprouts, radishes, carrots, celery, and chives just to name a few. My new favorite is with cauliflower. It’s so good, it even prompted a new tag “this is why you were given tastebuds”! How many recipes out there are this flexible while being insanely delicious.

It’s also a satisfying sandwich for meat-eaters (you could even top a burger with it), yet has ingredients you probably have on hand if you eat a lot of vegetarian meals. And that’s why you should be running to your kitchen right now. It pleases the masses. Below is the base recipe that I started off with, but experiment to your heart’s content. I won’t judge what you put between your buns.

    Ever thought of using mayo on your bread? One of my fndires told me that her grandmother spreads mayo on the bread before grilling it so it gives it a more rich flavor. Just a thought. I’ve never tried it so i don’t know how it tastes, but my friend swore she’s never had better tasting grilled cheese than her grandma’s but of course it could be her being a bit bias.
