How to Make It
Preheat oven to 350°F.
Place potatoes in a saucepan; cover with water. Bring to a boil over high. Reduce heat; simmer 20 minutes or until tender. Drain.
Return potatoes to saucepan. Add milk, 2 tablespoons oil, 1/2 teaspoon kosher salt, 1/4 teaspoon pepper, and cheese; mash to desired consistency.
Heat remaining 1 tablespoon oil in a Dutch oven over medium. Add onion and garlic; cook 4 minutes, stirring frequently. Add mushrooms and thyme, sauté 10 minutes or until mushrooms are tender. Add lentils, bulgur, stock, wine, soy sauce, 1/4 teaspoon salt, and 1/4 teaspoon pepper. Simmer 15 minutes or until thickened. Stir in green peas.
Spoon lentil mixture into a 13- x 9-inch glass or ceramic baking dish coated with cooking spray; top with mashed potato mixture. Bake at 350°F for 20 minutes or until heated through. Sprinkle evenly with chives.
