Now that we are vegan, she continues to make them, and they are even better. An easy series of subs: vegan butter for butter (we use Earth Balance), unflavored soy milk for milk, soy ground beef for the dead stuff (Boca crumbles are the best), and water mixed with a little of the flour for the eggs. You can also bread with plain flour if you don't find vegan bread crumbs.
