Oh, more- some of my kids really like saag aloo and it is very healthy!
Also we do a lot of baked French fries when I don't have a little baby. Just chop up potatoes into fry shapes, salt, and baked on lightly greased or silicone pans. I know most people wouldn't consider that lunch but we do.
I don't make them now since I don't have time to peel potatoes and I miss them.
We make pita pizzas a lot. I don't know healthy those are but they aren't terrible for you and they are fairly cheap (we get pita breads at Costco) and everyone likes them.
Oh, and sushi bowls. Just make a bunch of sushi rice and chop up toppings (we use seaweed, cucumber, avocado, sesame seeds, and ginger). Then we throw all that stuff in a bowl- much easier than making sushi.
Pancakes can be fairly healthy depending on how you make them, and they are definitely cheap and easy.
Do you ever eat potato pancakes? Those are cheap and yummy, too. I like them with applesauce.
