Prepare the Ingredients: Clean and slice the mushrooms, wash the spinach, mince the garlic, and squeeze fresh lemon juice.
Sauté the Mushrooms: Heat olive oil in a skillet over medium heat. Add mushrooms and cook until golden brown, stirring occasionally to allow moisture to release and caramelization to occur.
Add the Garlic: Stir in the minced garlic and cook for about 30 seconds until fragrant, being careful not to burn it.
Incorporate the Spinach: Add the spinach to the skillet and stir gently until wilted, about 1-2 minutes.
Season & Finish: Add salt, black pepper, and lemon juice, tossing everything together for a final burst of freshness.
Serve Immediately: Enjoy hot as a side dish or use it as a topping for grains, pasta, or proteins.
