‘Sunday Supper’ is dishing up vegan versions of Italian favorites like Lasagna, Mozzarella Sticks, Eggplant Parm and more. With traditional Sunday family dinners taking all day to prepare, Sunday Supper gives you, your time back, without sacrificing flavor, with frozen meals that are fully vegan, and non-GMO.. Founded by Richard Klein after wowing enough non-vegans with his lasagna, he knows what sets these dishes apart is taste. Sunday Supper partners with award-winning chefs to master just that, and I can attest that in the taste category, they’re unmatched.
