Sauteed Green Vegetables

Slice leeks into half-moons, then rinse thoroughly and pat dry. In a large skillet, melt butter over medium-high. Add leek, season with salt and pepper, and cook until translucent, 6 minutes. Add peas and cook, stirring frequently, until bright green and warmed through, about 6 minutes. Stir in spinach and cook until wilted, 2 minutes. Season to taste with salt and pepper.
