I also am trying to not eat any sugar, white flour or white rice for me because I am trying to loose weight.  So I make a LOT of stir frys, but they get old.  Chicken stirfrys, tofu stir frys, with veggies and either brown rice or whole wheat noodles.  What else can I make with tofu thas is super quick?  My son likes tofu as cubes, he won't eat "scrambled" tofu

 

Pretty impressive that he eats stirfrys. Lots of kids that age don't like food mixed together, like stews, pot pies, etc.  Or food with different textures. Or anything that is "slimy" or spicy. And my kids are a lot older and they still refuse to eat tofu scrambles.

I suggest trying some simple baked tofu recipes.  Also the ones where the tofu is breaded then fried or baked.  Whole grain pancakes and waffles are a completely acceptable dinner food IMO.  For beans, maybe try bean burgers where you puree everything in the food processor so it is a consistent texture (like the different ones Dreena Burton has in her books). When I make the Isa chickpea cutlets I make them with half chickpeas and half white beans so they are not so beany tasting and I puree the tar out of them before adding the other ingredients.

It took a long time before my kids would eat beans straight up.  Almost every dish that is their favorite comfort food today was rejected several times when first served. Another favorite is the chickpea stew in Madhur Jaffrey's World Vegetarian but it is only in the past year that I stopped mashing it up with a fork to make a smooth, gloppy puree of sorts and spooning it into a pita pocket.  Now they eat it in a bowl but it took, like, eight years.    Black-eyed peas and green peas with pasta shells and margarine--it's okay if he picks out the shells and just eats those the first ten times you serve it.  Some day he might pick up his spoon and eat the rest of the stuff at the bottom of the bowl.

We used to eat a LOT of soup. I could make it the night before so it was ready when I got home from work the next day. We'd eat it with some kind of biscuit or cornbread.

Nava Atlas wrote a book "The Vegetarian Family Cookbook" which is vegetarian but has vegan substitutions. It has my favorite waffle recipe and also a great recipe for mock chicken noodle soup.  I don't cook a lot of other recipes from the book, but I do remember finding comfort in the fact that at the end of every recipe she would make suggestions for what to do with picky eaters--how you could separate the different components of the meal into something younger kids might eat.  I felt reassured that I was not alone.
