Pasta Fazool
Here's a vegan dish that the kids would eat - pasta fazool. There are many recipes. The one I chose uses canned beans and mostly ingredients that you can keep on the shelf. It's a recipe that you can vary to fit what you have around.
One tip: leave out the pepper, a frequent turnoff for my kids at least. You can easily add pepper at the table from the pepper shaker - easy peasy.
It goes well with some Italian bread, or even cornbread.
