Buttery Spinach, Leeks and Mushrooms

INGREDIENTS
1 tablespoon butter
1 tablespoon extra-virgin olive oil
1 cup sliced portobello mushrooms
1/2 cup thinly sliced leeks
1 clove garlic, minced
1/4 cup vegetable broth
1 tablespoon heavy whipping cream
1 teaspoon fresh lemon juice
1/8 teaspoon salt
2 cups fresh baby spinach
1/4 cup grated Parmesan

DIRECTIONS
In a large skillet, melt the butter and olive oil together over medium-high heat. Add the mushrooms, and cook until they begin to soften, about 3 to 4 minutes. Add the leeks and garlic, and cook until tender, about 3 minutes. Add the broth, cream, lemon juice, and salt; cook for 2 minutes. Stir in the spinach, and lower the heat, stirring frequently, until the spinach is wilted, about 2 minutes. Sprinkle in the cheese and stir to combine. Transfer to a serving bowl and serve immediately.
