I love sandwiches because they are very versatile and you can customize them according to your tastes and needs. When spring is knocking at the door, I like to keep my meals simple and reduce meat consumption. Spring is the perfect time of the year to love a couple of pounds and to prepare for the beach season. It is best to start earlier to make sure you’re on time. Also, we’re all busy, and preparing complicated dishes is more of a luxury. Therefore, healthy sandwiches are a great choice for the times when you’re running against the clock.

How to saute mushrooms and spinach?

The goods news is that it is very easy to recreate this recipe. It involves sauteing the mushrooms and the spinach with spices then placing them on a loaf of fresh baguette.  But let’s take it to step by step.

When choosing the mushrooms for a sandwich, my vote goes to the brown champignons. Also known as  Baby Bella or Cremini mushrooms, these champignons have an earthier flavor than the whites. I consider being worth spending a bit extra for the creminis as they give out a bolder mushroom flavor.  Your mushroom spinach baguette will have a richer, nutty-tasting flavor. Isn’t that something you’d want from a sandwich?

Getting back to the recipe, first, clean and slice the mushrooms. Make sure you don’t cut them in small pieces because they will reduce in size during cooking. Just wipe away the dirt and cut off the mushroom stems. Then place them caps-side down and slice them in about 5-6 equal parts, perpendicular to the cutting board.

Heat up a frying pan and add the olive oil. In the meantime peel and chop the onion and the garlic then sautee it for about 2 minutes. Add the mushrooms to the pan and fry them for about 5-7 minutes, or until all the liquid evaporates. Remember to salt it, and sprinkle some granulated garlic on top. That will only enhance the taste. The first part of the cooking process is done, let’s proceed to the second.

How to saute the spinach?

Transfer the sauteed mushrooms to a plate and wipe off the pan/skillet with a paper towel. Put it back on the stove and drizzle only a few drops of olive oil. Add the baby spinach leaves to the hot surface and mix. Make sure you mix often as the spinach will be cooked in less than 30 seconds. You don’t want the leaves too mushy, let them be half-way through penetrate by the heat.  Put the spinach on the plate next to the cooked mushrooms. Let’s assemble the mushroom spinach baguette.
