PIN Spinach Salad with Mushrooms to try it later!
Spinach Salad with Mushrooms and Feta is a recipe that was inspired by another favorite spinach salad that has Bacon. Of course, bacon is always good, but I came up with this version of spinach salad with mushrooms when I was cooking regularly for my dad and my stepmother Norma who didn’t eat pork. And we loved the spinach salad using nicely-browned mushrooms instead of bacon.
And if you’re buying those big packages of spinach from Costco and realizing how hard it is to use up that much spinach, this salad is a great idea for using spinach that’s in the fridge. And any time you’re cooking for people who don’t want meat, I bet they’re going to love this meatless spinach salad that’s still loaded with delicious ingredients.
I promise you, this salad is going to be a hit with anyone who’s a spinach salad fan who likes mushrooms; I hope you will try it!
