PIN Balsamic Spinach Salad to try it later!

This Balsamic Spinach Salad with Mushrooms and Feta is a recipe that was inspired by Spinach Salad with Bacon and Feta. I came up with this version years ago when I was cooking dinner regularly for my dad and my stepmother Norma; she didn’t eat pork, so I used nicely-browned mushrooms instead of the bacon. And for years this absolutely-delicious salad recipe was back in the archives of the blog with a photo that wouldn’t entice anyone to try it!

Then I started buying those big packages of spinach from Costco and realizing how hard it is to use up that much spinach. And when I remembered this salad I loved the idea of a meatless spinach salad that was still loaded with delicious ingredients. I promise you, this salad is going to be a hit with anyone who’s a spinach salad fan, but go ahead and add a little bacon if you prefer!

Notes

Eight cups of spinach leaves is about 7 ounces of spinach. I used brown Cremini mushrooms, but use any mushrooms you prefer.

Use any all-purpose seasoning blend if you don't have Spike Seasoning.

I used my new favorite Feta Cheese for this recipe.
