This Shepherd's Pie is vegetarian comfort food at its best. Carrots, mushrooms, peas, and green beans bathed in a creamy sauce and topped with cheesy mashed potatoes make a diner's delight!
Everything you love about Shepherd's Pie, but this quick and easy version is made in the pressure cooker! Pressure cook the potatoes on top of the filling, then mash, assemble the casserole and serve. So easy!
