<a href="http://www.cok.net/lit/recipes/" target="_blank">here</a> has a few. Some of them involve tofu, but some of them don't, and they are all very simple. All those recipes are vegan, but I imagine you can use cow milk in place of soymilk, etc, if your kids are lacto-ovo and you don't want to buy more specialist stuff in.<br><br><a href="http://veganlunchbox.blogspot.com" target="_blank">lunchbox ideas</a> many of which could be used for eating at home too. This site doesn't update (often) anymore, but there are plenty of ideas from lunches past.<br><br>
Plus of course there are meals that everyone eats that are veg friendly, such as macaroni & cheese, vegetable soups, salads (although I know many kids would refuse this, and they can leave you hungry unless you bulk them up with nuts and other proteins), etc.<br><br>
Buying in veggie burgers & veggie sausages are an easy way to replace meat. Serve them in buns, or just with vegetables.
