MUSHROOM, ONION, AND SPINACH SANDWICH



Mushroom, Onion, and Spinach Sandwich image

We love this recipe. It's fast, easy, tastes good, and is healthy. I found it on one of my favorite blogs, CuisineNie (aka nieniedialogues.blogspot.com), but, since CuisineNie is now closed, I thought I'd put this recipe back out there. The amounts of onion, mushrooms, garlic, spinach, vinegar, and cheese are all approximate and should be altered according to your tastes. The recipe is pretty flexible; you can use different types of mustard, cheese, etc.. We like this served with canned Progresso lentil soup.

Tips:

  • Use fresh ingredients. Fresh mushrooms, onions, and spinach will give your sandwich the best flavor.
  • Don't overcook the mushrooms and onions. They should be cooked until they are soft and tender, but not mushy.
  • Season the mushrooms and onions well. Salt, pepper, and garlic powder are all good choices.
  • Use a good quality bread. A hearty bread like sourdough or whole wheat will hold up well to the sandwich fillings.
  • Spread the mayonnaise or butter on the bread before adding the fillings. This will help to keep the bread from getting soggy.
  • Add a layer of cheese to the sandwich. Cheese will help to melt the ingredients together and make the sandwich more gooey.
  • Serve the sandwich warm. This is the best way to enjoy the flavors of the sandwich.

Conclusion:

The mushroom, onion, and spinach sandwich is a delicious and easy-to-make sandwich that is perfect for lunch or dinner. It is packed with flavor and nutrients, and it is sure to be a hit with everyone who tries it. So next time you are looking for a quick and easy meal, give this sandwich a try.
