Make it a Meatless Monday with these hardy vegetarian tacos, stuffed with mildly spiced cauliflower and mushrooms and topped with sweet bell pepper sauce. This mostly hands-free meal is perfect for a busy week night, because you get 20 extra minutes to relax while dinner is roasting. Round out this meal with a side of pinto or black beans and Mexican hot chocolate for dessert. This is also a great make-ahead meal, especially if you are entertaining. Reheat the vegetables, make a pitcher of margaritas and you are ready to host book club.
