Ingredients

Instructions

  1. Step 1: Heat 2 tbsp extra-virgin olive oil in a large skillet over medium heat. Add 3 thinly sliced garlic cloves and sauté for 1-2 minutes until fragrant and lightly golden.
  2. Step 2: Add 8 oz sliced cremini mushrooms to the skillet, stirring occasionally. Cook for 5-6 minutes until the mushrooms release moisture and become tender and slightly browned.
  3. Step 3: Add 10 oz fresh baby spinach, 1/2 tsp sea salt, and 1/4 tsp black pepper to the skillet. Stir frequently until the spinach wilts completely, about 3-4 minutes.
  4. Step 4: Remove from heat and sprinkle 1 tsp lemon zest over the vegetables. Toss gently to combine and serve warm as a bright, savory Whole30 side dish.
